The user must enter data as detailed below.
NETWORK_ID – The network that is carrying the data. Data will be received via all peer controllers
that share this network identity. Range 1 – 8.
SOURCE_PEER_ID – The peer that is sending the data. Range 1 – 40.
SOURCE_DATA_ID - Unique data block number defined at the output board. Range 1-64.
REFRESH_TMO - The maximum number of milliseconds allowed between successive refreshes of
input data before the data is declared invalid. Note that following this time the input data will either
retain the last received values or revert to a fail-safe condition according to the state of control rack
variable 1. Range 1-10000.
FS_VALUE - Control value adopted by inputs when input is status has failed. Where input
corresponds to an integer, fractional part is truncated. This value is always adopted at application
start-up, though it will not be used again while RACK 3:Variable 1 is set TRUE. Range -
9.999999e+38 to +9.999999e+38.
