Input Data File

The input data file provides access to input data for use in the control program,

over-range indication for the input and output channels, and output data feedback

as described below.

IMPORTANT

Input words 6 and 7 contain the Output Data Echo/Loopback

information for output channels 0 and 1 respectively. Bits 0

through 6 and Bit 15 of words 6 and 7 should always be set to

zero in your control program. If they are not set to 0, the invalid

data flag (Ex) will be set for that channel by the module.

However the channel will continue to operate with the

previously converted value.
