The base 100 SE has no digital communication (no RS-485, no Modbus). Some late-production “SE-R” variants had optional RS-485, but they are rare. Make it better: You cannot add comms. However, you can make the system better by using the 4-20mA analog retransmission option (if fitted) to send PV to a PLC analog input. Without that, consider this a reason to replace (see Part 5). However, you can make the system better by
