WARNING
Extreme caution must be used when writing port calibration values to registers 211 through 218 (40212 thru 40219). Only
values read from these registers shall be written to them. The purpose of these registers is to allow the network host to
store the port calibration values and then write them back to the actuator in case of replacement of the CPU module.
Foundation Fieldbus (FF)
The MPA uses a CAM18 to convert between Modbus and Foundation Fieldbus. Refer to Bettis M2CP CAM18 & TEC2000
CAM218 Installation, Operation and Instruction Manual for installation and setup of the FF link. Relations between the
Modbus and FF maps are identified as follows.
