Can the HMC be configured as a Modbus TCP master and a slave at the same time?

Yes, the HMC can be configured as a Modbus TCP Master on COM3 and still retain the default Modbus TCP Slave configuration.

You must choose one or the other between master and slave for Modbus RTU, but Modbus TCP can be both simultaneously thanks to Ethernet. As a master (client) you can read Modbus data from, or write Modbus data to, other Modbus TCP devices.

Logic Blocks are commands required to create complex ladder logic routines for your PLC application. Our HMI+PLC (HMC) and PLC (MLC) configuration software MAPware-7000 contains more than one hundred logic block instructions. This provides the…

What is IEC 61131-3?

IEC 61131-3 is a section of an International Electro-Technical Committee (IEC) standard that provides a definition for implementing PLC programming software.

The standard was first introduced in 1993 as the result of an effort to standardize the myriad PLC logic editors in the automation marketplace. The goal of the standard is to give automation professionals a familiar environment and set of tools to create PLC programs across vendor platforms.
