Input and Output Bit Patterns Vary by Product
Input and output bit patterns vary by product. For example, the 6250's input pattern
comprises 24 general-purpose inputs (bits 1-24) and 2 trigger inputs (bits 25 & 26); in
contrast, the OEM6250's input pattern comprises 16 general-purpose inputs (bits 1-16) and
2 trigger inputs (bits 17 & 18). To ascertain the bit pattern for your product, consult the I/O
bit pattern table on page 107.
Outputs
The following steps describe the use and function of the OUTEN command.
Step 1
Display the state of the outputs with the TOUT command:
TOUT ; Displays the state of the outputs
The response will be:
*TOUT0000_0000_0000_0000_0000_0000_00
Display the function of the outputs with the OUTFNC command:
OUTFNC ; Displays the state of the outputs
The response will be:
*OUTFNC1-A PROGRAMMABLE OUTPUT - STATUS OFF
*OUTFNC2-A PROGRAMMABLE OUTPUT - STATUS OFF
*OUTFNC3-A PROGRAMMABLE OUTPUT - STATUS OFF
.
.
*OUTFNC26-A PROGRAMMABLE OUTPUT - STATUS OFF
Step 2
Disable outputs 1 - 4, leave them in the ON state.
OUTEN1111 ; Disable outputs 1-4, leave them in ON state
OUTFNC ; Displays the state of the outputs
The response will be:
*OUTFNC1-A PROGRAMMABLE OUTPUT - STATUS DISABLED ON
*OUTFNC2-A PROGRAMMABLE OUTPUT - STATUS DISABLED ON
*OUTFNC3-A PROGRAMMABLE OUTPUT - STATUS DISABLED ON
.
.
*OUTFNC26-A PROGRAMMABLE OUTPUT - STATUS OFF
Step 3
Change the output state using the OUT command. The status of all outputs, including
auxiliary outputs, is displayed. The output bit pattern varies by product. To determine the bit
pattern for your product, refer to the OUTEN command description.
OUT1010 ; Activates outputs 1 and 3, deactivates outputs 2 and 4
Display the state of the outputs with the OUTFNC command.
OUTFNC ; Displays the state of the outputs
The response will be:
*OUTFNC1-A PROGRAMMABLE OUTPUT - STATUS DISABLED ON
*OUTFNC2-A PROGRAMMABLE OUTPUT - STATUS DISABLED ON
*OUTFNC3-A PROGRAMMABLE OUTPUT - STATUS DISABLED ON
.
.
*OUTFNC28-A PROGRAMMABLE OUTPUT - STATUS OFF
Notice that output 2 and output 4 have not changed state because the output (OUT) command
has no effect on disabled outputs.
Step 4
To re-enable the outputs, use the OUTEN command.
OUTENEEEE ; Re-enables outputs 1-4
