What program is used to code the PLCs?

CICON

What is the maximum number of I/O supported by the PLCs?

  • PLC-S: up to 384 I/O points
  • PLC-S PLUS: up to 512 I/O points

What is the maximum number of relay outputs for a chassis?

Up to 48 relay outputs per chassis

How many CM3-SP01EET modules can be installed on one chassis?

Up to 5 modules per chassis

Do CIMON PLCs support Modbus?

PLC-S:

  • Modbus RTU Master/Slave
  • Modbus TCP Slave (requires CM3-SP01EET module)

PLC-S PLUS:

  • Modbus TCP/RTU Master/Slave

Why is Modbus TCP not communicating correctly on the PLC?

Make sure to uncheck the Auto-Transmit option for data.

Which CPUs support positioning?

All of the below CPUs support built-in positioning.

  • CM3-SP16MDTF
  • CM3-SP16MDCF
  • CM3-SP16MDRF
  • CM3-SP32MDTF-SD
  • CM3-SP32MDCF-SD

What can I do if my PLC doesn’t support positioning?

You can add a CM3-SP02POS module, which provides an additional 2 axes for positioning.

How many axes can a PLC control?

  • Built-in CPU positioning: 2 axes
  • PLC-S with modules: up to 22 axes
  • PLC-S PLUS with modules: up to 30 axes

How do I update the firmware on my PLC?

To update the firmware on your PLC:

  • Connect to the PLC.
  • Go online.
  • Select Firmware Upgrade.
  • Choose the firmware file path.
  • Download the firmware.
  • Switch the PLC to Stop Mode.
  • Perform a power cycle.
  • Switch the PLC back to Run Mode.

What modules are C1D2 rated?

The following modules are C1D2 rated:

  • PLC-S PLUS CPU
  • SP32EDOP
  • SP32EDCP
  • SP16EOR
  • SP04EAA-A
  • SP04ERO-A
  • SP04ETO-A
  • SP02HSC
  • SP02POS

What is a Watchdog Timer in a PLC?

A Watchdog Timer ensures that the PLC program executes within a specified time limit. If the program exceeds this time, the Watchdog Timer triggers a fault to prevent system errors or unintended behavior.

What is a redundant PLC system?

A redundant PLC system includes a backup CPU that automatically takes over if the primary CPU fails, ensuring continuous operation and minimizing downtime.

How do I add expansion modules to a PLC?

To add expansion modules to a PLC:

  • Install the modules in the correct slots, securing them with the clips on the sides.
  • Configure the modules properly within CICON software to ensure they are recognized and operational.

What is a PID loop in PLC programming?

A PID loop is a control function used in PLC programming to maintain precise and stable process control.

What is retentive (non-volatile) memory in a PLC?

Retentive memory is a type of memory in a PLC that preserves stored data even after the device is powered off or restarted.

Can a PLC run without an HMI?

Yes. A PLC can operate on its own without an HMI, though an HMI is often used for easier monitoring and interaction.

Can I simulate my PLC program before downloading it?

Yes. With CICON, you can use the built-in simulator to test and configure your PLC program in a virtual environment before deploying it to physical devices.

How do I reset a PLC to factory settings?

In CICON, this can be done via: Online → PLC Reset → Factory Reset.

What programming languages are used for PLCs?

Common PLC programming languages include

  • Ladder Logic
  • Structured Text
  • Function Block Diagram (FBD)
  • Sequential Function Chart (SFC)
  • Instruction List (IL).
