With Ethernet port of M17xP, Modbus TCP client is not available, user can use "Binding" to read data from other M17xP. Define more than one device in the same connection project and share the variables.
When user configures Ethernet port as Master, a binding object can be added under it. Add it if a device wants to READ objects from other ones
The set of PLC objects can be sent or received is made of:
-- EEPROM parameters, created with Application (not BIOS).
-- Status variables, created with Application (not BIOS).
Each controller can read up to 128 variables from all the others, so assuming a balanced network each of the M172P can read 128/3 variables from each of the others.
User may refer the the TCP Binding Guide and sample program from attachment
