The table below shows the physical connection possibilities for Mint products supporting integrated Modbus protocols. AC500 and
CP600 products are included for reference.

When using Modbus RTU consideration must be given to the above table if there are multiple slave devices. For example, if the
system comprises a CP600 HMI as the Modbus master and a NextMove ESB-2 and AC500 Eco PLC as slave devices then it is not
possible to connect all of these together on the same serial network as they share no common connection types. A system like this
would require the HMI to operate using two protocols (e.g. Modbus TCP to the Eco PLC using the Ethernet PLC variant and
Modbus RTU to the NextMove ESB-2 using either RS232 or RS422).
The following tables show the pinouts of the various products for each connection type:
