Wire The Module; Communicate With The Module - Rockwell Automation Allen-Bradley C Series Installation Instructions Manual

Wire the Module

WARNING: If you connect or disconnect wiring while the field-side power is on, an electrical arc can occur. This could cause an explosion in hazardous location
installations. Be sure that power is removed or the area is nonhazardous before proceeding.
Figure 2 - POINT I/O VHSC Module

Communicate with the Module

POINT I/O modules send (consume) and receive (produce) I/O data (messages). You map these data onto the processor memory.
These modules produce 6 or 10 bytes of input data (scanner Rx) and fault status data. These modules consume 2 or 4 bytes of I/O data (scanner Tx).
Use Parameter
23 and 24
25
Set parameter 25 to zero to re-enable parameter 4, active output.
Default Data Map
Message size: 6 or 10 Bytes

Channel 0 value of present counter state (LSW)
Produces (scanner Rx) Channel 0 value of present counter state (MSW)
PE EF
LSW = Least significant word
MSW = Most significant word
PE = Programming error
EF = EEPROM fault status
NR = Not ready status bit
FS = Output fault status bit – bit 10 for output 0, bit 11 for output 1
Where:
OS = Output on/off status bit – bit 8 for output 0, bit 9 for output 1
ZS = Z input status
BS = B input status
AS = A input status
C = Stored data count
ZD = Zero frequency detected
