4.2.4 Modbus TCP Functionality
The Modbus TCP Modbus communication module offers the following functionality:

Dual switched RJ45 communication ports
 256 bytes of I/O data in each direction

100 Mbps full duplex

Supports 4 simultaneous (master) connections
All Modbus functions and addresses available are detailed in Chapter 5 “Modbus RTU
Communications Table”
Synergy uses Protocol Addressing (Base 0); not PLC Addressing (Base 1). If you are not using the
correct selection, all the addresses will be off by 1. Recommended test: monitor a non-critical
parameter such as Start Time (address 7104), then manually change the value on the touchscreen
and verify that Modbus master actually sees the correct changes.
