PLC-based machine control
Specify the controller, its connected devices and the timing you need at the machine. This page focuses on PLC-based motion control, using Megmeet’s MC5000 family as a worked product reference—not as a specification for every industrial control system.
01
The parameter table above asks for exact supply and temperature limits. Beckhoff's technical data for its CX7000 compact controller shows what a complete answer looks like: power supply 24 V (−15%/+20%), operating temperature −25…+60 °C, storage −40…+85 °C, relative humidity 95% without condensation, protection rating IP20, and vibration/shock and EMC conformity named by standard (EN 60068-2-6/-27, EN 61000-6-2/-4). [4]
Editorial calculation: 24 V −15% is 20.4 V and +20% is 28.8 V, so the 24 V supply and its wiring must hold the controller within that band under load. An IP20 rating means the controller goes inside an enclosure; specify the cabinet rating separately. [4]
For the integrated digital inputs the same page cites EN 61131-2 type 3, with a signal “0” of −3…+5 V, a signal “1” of 11…30 V and a configurable input filter (standard 3 ms, minimum 10 µs); outputs are rated 24 V DC, 0.5 A. Ask your supplier for the same fields — supply tolerance, IEC/EN 61131-2 input type, filter time and output current — for each CPU and I/O module in the quotation. [4]
| Field | CX7000 published value | Ask for your controller |
|---|---|---|
| Power supply | 24 V (−15%/+20%) | Tolerance and maximum current |
| Operating / storage temperature | −25…+60 °C / −40…+85 °C | Ratings for CPU, modules and HMI |
| Humidity, protection | 95% no condensation; IP20 | Enclosure rating for the cabinet |
| Digital input type | EN 61131-2, type 3; filter 3 ms standard, 10 µs minimum | Input type and filter range |
02
Megmeet offers pulse-motion and EtherCAT-motion variants, with a separate motion-control CPU described in the family brochure. Select the exact controller and drive interface before counting axes. The family maximum is not a capability of every part number. [1] [3]
List coordinated groups, cam axes and future options alongside the total. A larger CPU suffix does not prove the required group can run at the advertised minimum cycle. Ask for a demonstrated configuration with your drive models and load. A later CPU change requires a compatibility and commissioning review; it does not necessarily require wholesale rewiring. [1]
| Item | Pulse motion | EtherCAT bus motion |
|---|---|---|
| Axis capacity | The brochure’s family headline is up to 38 pulse axes. MC5100EA has six 2 MHz differential pulse outputs; MC5000-8PO adds eight 200 kHz axes per module, with up to four modules stated. Confirm the supported CPU/configuration. [1] | MC5000 bus variants are offered for 8, 16, 32 or 64 axes. The suffix matters. [1] |
| Command interface | Confirm pulse mode and electrical levels at each drive. The 8PO table lists pulse/direction, forward/reverse and AB modes; one universal “pulse-and-direction pair” is not a wiring specification. [1] | Commands and status depend on the drive profile and mapped process data. ETG describes cyclic exchange and profiles including CiA 402; not every device implements every profile. [2] |
| Feedback and diagnostics | Specify how encoder, ready, fault and limit signals reach the controller. Pulse command wiring alone does not define the feedback architecture. [1] | Request the actual position/status objects, update rates and fault behavior in the tested drive configuration. A bus connection alone does not establish which values are exchanged. [2] |
| Expansion and wiring | List pulse outputs and high-speed inputs separately from ordinary I/O. Confirm terminal assignments and the expansion-module limit. [1] | Show drives and remote I/O on the topology drawing, including cable lengths and junction devices. EtherCAT supports line, tree and other topologies, not only one daisy chain. [2] |
03
In Megmeet’s application diagrams, field signals reach local or remote I/O, the PLC executes the application, and pulse or bus commands reach drives. The HMI exchanges operating data over the selected communication link. The final motor, valve or other actuator is part of the machine scope and must also be identified in the order. [1]
| Functional component / BOM reference | Role in the assembly | What the quotation must identify |
|---|---|---|
| Programmable logic controller | Runs the application and coordinates the selected motion functions. | Exact CPU, firmware and programming environment. The 202405 brochure distinguishes E, EA and EB variants; their I/O cannot be substituted by name alone. [1] |
| Human–machine interface | Displays operating information and accepts the configured operator commands. | HMI model, project file, communication mapping and the actions enabled for each user. The brochure shows an MZ800-series HMI in an application example, not an HMI included with every CPU. [1] |
| Input/output modules | Connect discrete signals and convert the specified analog or temperature channels. | Input type, output type, channel count, isolation, conversion time and terminal assignment. Analog resolution is not the accuracy of the finished control loop. [1] |
| Communication interfaces and remote-rack head | Connect the controller, drives, distributed I/O and supervisory equipment. | Identify integrated ports and separately supplied modules. MC5000S-ET, S-EIP and S-PN refer to different remote-rack protocols; they are not interchangeable adapters. [1] |
| Power-supply unit | Provides the specified electrical supply to the control hardware. | Power model, input range and a load schedule for logic, I/O and field devices. The MP50AC220 is listed as 24 V / 2 A output; the brochure disagrees internally on its AC input range. [1] |
| Sensors and signal connections | Provide the position, process and machine-state information used by the application. | Sensor models, ranges, output types, cables, shielding and connection drawings. The brochure illustrates a color sensor for registration; it does not specify a universal sensor set. [1] |
This is a functional order checklist, not a fabrication BOM or a promise that all six items ship with the PLC. The reviewed brochure does not establish housing, PCB, terminal, display-glass or cable material grades for the complete assembly. Request model-specific declarations where the environment requires them.
04
The table below follows the brochure’s CPU-series list on printed pages 9–10. Read both the family letters and axis suffix. High-speed capability can be a function of an existing terminal; do not add it again as extra physical I/O. [1]
| CPU model | Built-in I/O | Motion |
|---|---|---|
| MC5200E | 16 inputs / 16 transistor outputs | General main module; no EtherCAT motion-axis count in the series list. [1] |
| MC5100EA | Four 200 kHz pulse inputs and three 1 MHz differential inputs; four transistor outputs and six 2 MHz differential pulse outputs | Pulse-motion main module. Obtain the pin and mode allocation for simultaneous use. [1] |
| MC5000E8 / E16 / E32 / E64 | 16 inputs / 16 transistor outputs | 8 / 16 / 32 / 64 EtherCAT axes respectively. [1] |
| MC5000EA8 / EA16 / EA32 / EA64 | EA-series pulse-input and differential-output arrangement, as listed above | 8 / 16 / 32 / 64 EtherCAT axes respectively; confirm combined bus/pulse operation. [1] |
| MC5101EB; MC5001EB8 / EB16 / EB32 / EB64 | Eight inputs and eight outputs, each side supporting four 200 kHz high-speed channels | MC5101EB is the pulse variant; MC5001EB suffixes identify bus-axis capacity. The main table separates general and high-speed channels; do not count them twice. [1] |
MC5000-0064ETN is a 64-point transistor output module, not a CPU. The brochure’s unlabeled main-module dimension table must not be reassigned to that output-module code. Model-specific terminal and installation drawings remain required. [1]
05
ETG describes EtherCAT’s design goals as cycles of 100 µs or less and synchronization jitter of 1 µs or less. Megmeet advertises a 250 µs control cycle for this family. Neither statement is a measured sensor-to-actuator response for your machine. [2] [1]
Request the exact drive firmware, EtherCAT Slave Information file, supported drive profile and mapped process data used for acceptance. ETG lists separate communication profiles, including CoE, SoE, EoE, FoE and AoE; sharing an EtherCAT label does not establish application-level compatibility. Ordinary EtherCAT communication also does not establish a functional-safety claim: Safety over EtherCAT is a separate protocol and system consideration. [2]
ETG describes optional Ethernet-over-EtherCAT mailbox tunnelling. Do not assume every device offers it, or that an ordinary Ethernet switch can be inserted into a chosen EtherCAT line without an engineered topology. Identify HMI/MES traffic and the physical interface used for it. [2]
06
| Parameter | What must be measured or specified |
|---|---|
| I/O capacity · points | Separate CPU terminals, local expansion and remote racks, then list actual module codes and power demand. The family maxima are not a delivered configuration. [1] |
| Processing speed · ms | State the program and test conditions. The brochure gives both 2 and ≤2.2 ms for its 100K-step benchmark; neither is your machine’s complete response. [1] |
| Communication protocols | Name the interface, role and device profile: EtherCAT motion/remote I/O, Ethernet Modbus TCP, or RS485, as applicable. A protocol list without the matching ports and roles is insufficient. [1] [2] |
| Operating temperature · °C | Obtain the exact CPU, module, HMI and enclosure limits. The brochure’s analog accuracy test temperatures do not establish an ambient rating for the complete system. [1] |
| Supply · V AC/DC | The MP50AC220 series list says 100–240 VAC input; its power-specification table says 110–240 V, with 24 V / 2 A output. Confirm the ordered unit’s current manual and nameplate; neither range establishes every device’s DC tolerance. [1] |
| Control accuracy | Separate sensor error, analog-conversion accuracy and the process or axis acceptance criterion. Do not assign one “% of span” figure to the entire assembly or treat bit resolution as accuracy. The brochure reports individual module characteristics. [1] |
| Scan time · ms | Record the actual application task period and its variation under the agreed load, including communication and enabled functions. Keep it separate from the minimum bus synchronization period. [1] [2] |
| Memory | Specify ladder steps, C-program capacity and data allocation separately; also obtain retention, project/version and backup requirements for the selected firmware. [1] |
| Ingress protection | Request the rated CPU/module/HMI and enclosure surfaces separately. The reviewed sources do not establish a protection rating for the assembled panel. |
| Mounting | Obtain the selected models’ installation drawings, clearances, grounding and enclosure requirements. The brochure’s product pictures do not establish a universal rail/panel/rack mounting choice. [1] |
| Weight · kg | Request the exact controller and assembled-panel weights. The weight of one controller is not the shipping weight of an assembled cabinet. |
| Dimensions · mm | Require labeled width, height and depth for each module plus the assembled layout and cable clearances. Do not convert the brochure’s generic main-module drawing into a size for every MC5000 item. [1] |
07
The family catalogue establishes these module options. Match each part number to its signal, rack and power requirements; the presence of a catalogue entry is not a confirmed delivery commitment. [1]
08
The brochure describes Flash storage without battery maintenance, programming tools and diagnostics. That does not replace a machine project backup or define a maintenance interval. Obtain the supplier’s current service procedure for the assembled control system. [1]

Megmeet publishes the PLC family discussed here; LIENM describes automation-system work.
Publishes the MC5000 PLC and motion-control family with CPU and expansion-module model lists. Request the exact CPU, tested drives, firmware and module schedule; a group product page does not identify the manufacturing site or certify the complete machine.
Product scope checked 2026-10-10
Its cosmetic-processing equipment site lists Automation Control Systems and describes BAS/GMS/PWS work. This supports an integration enquiry, not a claim that LIENM manufactures the MC5000 or has validated a particular EtherCAT drive combination. Define responsibility for programming, panel supply and commissioning.
Product scope checked 2026-10-10
Explore company information and manufacturing capabilities, then discuss the scope of your project with a relevant supplier.
Choose against the required drive interface, coordinated motion, feedback and diagnostics. The MC5000 family includes pulse variants and bus models with up to 64 EtherCAT axes, but that maximum does not describe every CPU. Request a tested model/firmware and I/O configuration. [1] [2]
ETG describes design goals of cycles at or below 100 µs and synchronization jitter at or below 1 µs. A controller’s configured bus period, PLC program timing and measured machine response are distinct. Megmeet’s 250 µs family claim must be checked at the intended axis count and load. [2] [1]
ETG gives up to 100 m between 100BASE-TX nodes, not for the entire network. Longer links require suitable media, such as fibre, and compatible devices. Confirm the complete topology and cable specification. [2]
No. In Megmeet's 2024 brochure it is a 64-point transistor output module. [1]
Beckhoff's CX7000 technical data is one example: 24 V supply with −15%/+20% tolerance, −25…+60 °C operation, 95% humidity without condensation, IP20, and inputs to EN 61131-2 type 3. Ask for the same fields for your controller. [4]
