Byte 0/1
Setpoint channels 13 and 14
The actual values read in via channels 13 and 14 are compared with the setpoint
and checked for tolerance violations.
Input: 0 to 1024 units = 10.24 V or 0 to 2048 units = 20.48 V.
Byte 2
Positive tolerance channels 13 and 14
If the actual value is higher than the setpoint plus the positive tolerance, an error
identifier is set (bit 0 in the corresponding error byte). By entering value 0, the
tolerance processing is disabled.
Byte 3
Negative tolerance channels 13 and 14
If the actual value is below the setpoint minus the negative tolerance, an error
identifier is set (bit 1 in the corresponding error byte). By entering value 0, the
