1.9.3 Adding a Modbus Server/Slave Device
The MPiec controller can communicate with up to 20 unique IP addresses
simultaneously using Modbus TCP.
A maximum of 20 data blocks of various function codes can be configured
if necessary.
The minimum poll period or update interval is 4 ms (+4 ms
tolerance.) Note that MODBUS TCP is not a deterministic protocol. Setting
a very fast update interval is not recommended because it will increase the
load on the CPU. Fast updates and high priorities should be allocated
based on application requirements)
