Reading setpoint relay

The example process control gauge (PCG) command sequence assigns
relays 1 and 3 to the Convectron gauge and relays 2 and 4 to the differential
pressure sensor:
Example PCG command from host:
Response from module:
The 4-digit value following "PCG" assigns relays in ascending numerical
order. In this example, "CC" is the assignment for relays 1 and 2, and "DD"
is the assignment for relays 3 and 4.
• A "C" value assigns the specified relay to the Convectron gauge.
• A "D" value assigns the specified relay to the diaphragm differential
pressure sensor.
The example read process gauge (RPG) command causes the module to
return a value indicating that relays 1 and 2 are assigned to the Convectron
gauge (vacuum chamber pressure) and relays 3 and 4 are assigned to the
differential pressure sensor:
RPG command from host:
Example response from module:
The returned value indicates relay assignments in ascending numerical
order. In this example, "CC" is the assignment for relays 1 and 2, and "DD"
is the assignment for relays 3 and 4.
• A "C" value means the relay is assigned to the Convectron gauge.
• A "D" value means the relay is assigned to the differential pressure
sensor.
The read process control relay status (RPCS) command causes the module
to return a character string that represents the status of all four relays.
The example RPCS command causes the module to return a character string
indicating that relays 1 and 3 or activated and relays 2 and 4 are
deactivated.
RPCS command from host:
Example response from module:
• A value of 1 means the specified relay (1, 2, 3, or 4) is activated.
• A value of 0 means the specified relay (1, 2, 3, or 4) is deactivated.
