Periodic Data Transmitted PGNs

PGN 127501 – Binary Switch Bank Status

The SIM100 uses this PGN to transmit the state of each of the connected switch inputs

Field 1: Indicator Bank Instance – This field identifies the particular switch bank to which this

PGN applies. Please refer to Section 2.5.1 for instructions on how to program the

value of this field.

2: Indicator #1 – This field indicates the state of the switch connected to the SW1A and

SW1B inputs of the SIM100. The state will be one of the following values:

• “Closed” – The monitored switch is closed.

• “Open” – The monitored switch is open.

• “Error” – There is an open connection between the SIM100 and the monitored

switch. This state can occur only when the indicator is configured to use an

End of Line Resistor.

• “Data Not Available” – The indicator is configured as “Disabled”

3: Indicator #2 – This field indicates the state of the switch connected to the SW2A and

SW2B inputs of the SIM100.

4: Indicator #3 – This field indicates the state of the switch connected to the SW3A and

SW3B inputs of the SIM100.

5: Indicator #4 – This field indicates the state of the switch connected to the SW4A and

SW4B inputs of the SIM100.

6: Indicator #5 – This field indicates the state of the switch connected to the SW5A and

SW5B inputs of the SIM100.
