Not Used (Word 7) 0x0000
- = Not used. Bit set to 0.
S<x> = General status bit.
If a bit is set (1) then there is an error associated with that channel (i.e.
under/over range).
U<x> = Under range flag.
When set to 1, indicates the output word value set by the user is below the
defined Low Range value (see Output Data Format table). The channel will
output voltage or current (depending on the range type) to the Low Limit
value.
O<x> = Over range flag.
When set to 1, indicates the output word value set by the user is above the
defined High Range value (see Output Data Format table). The channel will
output voltage or current (depending on the range type) up to the High Limit
value.
LD<x> = Load Error. If the channel is configured for voltage mode, this bit indicates a
short circuit. If the channel is configured for current mode, open circuit is
indicated. The error bit is cleared (0) at the time the condition is cleared.
Section 3.6
Configuration
Ladder Sample
The following ladder sample demonstrates how to configure the module when the PLC
transitions from Program to Run, using the process described in Section 3.4.
!
Attention
Use the “Command” bit (B3:0/0) in the following ladder sample as a
condition before any instruction that writes data to one of the 8 module
output words. Failure to do so can result in the module rejecting the
configuration and not going into run mode (i.e. a rapid blinking module
status LED).
