Modbus Communications (Cont.) SCAN RATE OF DEVICE 0.5, 1 to 255 seconds selectable at configuration time. DEVICE ADDRESS RANGE 1 to 247 DATA TYPES TRANSFERRED 2-byte or 4-byte signed or unsigned integers, 4-byte IEEE single- precision floating values, or binary values. Byte and bit swapping are selectable. FBM224 Channel Isolation Each communication channel is galvanically isolated and referenced to earth (ground). The module can withstand, without damage, a potential of 600 V AC applied for one minute between either channel and earth. CAUTION This does not imply that the channels are intended for permanent connection to voltages of these levels. Exceeding the limits for input voltages, as stated elsewhere in this specification, violates electrical safety codes and may expose users to electric shock. Fieldbus Dual Communication Communicates with its associated FCM or CP via the redundant 2 Mbps module Fieldbus.
