I have reading error while reading a 32 bit holding register in a Honeywell masterlogic 50 PLC. I am using modbus TCP protocol to poll the PLC with inductive automation scada software.
We are working with masterlogic plc. we read a floating point variable using modbus TCP. The variable is an accumulator, suddenly the value drop in some units, and suddenly it increase in the same amount. This kind of behaviour is erratic. I thought could be a precision issue due to format difference between floating point in scada software and plc, but it seems to be the same. both manuals stand that use same ieee standard for floating point formatting.
Any comments I will appreciate
Regards
Luis
