Modbus Comms

I am using four Comap IntelliGen units connected to a GE Fanuc 9030 PLC via a IG-MU unit. Although I have established comms with the units using modbus protocol, I am having difficulty deciphering the alarm lists 24545 & 24571 (I have values coming into the registers but can't decipher them!). No problem with reading kW(8202) and list #1 (8317). Do you have any recommendations of the most efficient/easy method of manipulating these lists or even some sample code! (I am using Versapro software).

Kind Regards,

Patrick Borgman
