No, not all blocks have a direct Modbus address. For example On-Delay Timer setting does not have a direct address. However, you can use another reference block in your program to store the timer setting such as an AF or Counter block, which do have direct Modbus addresses.

Yes, the CPU can act as both a Modbus Master and Slave at the same time. For example you may connect the CPU via RS232 programming lead to one of our HMI’s, and set it to act as a Modbus RTU Slave. At the same time, you could have an RS485 expansion module attached to […]

Yes, by use of the Modbus Read and Modbus Write blocks in the programming software.

Yes, all the CPU’s in our range support Modbus RTU protocol as standard. Ethernet CPU’s also support Modbus/TCP protocol.
