4.4.5 Map Descriptor example 2 – Monitoring Analog Loop Devices
Analog devices on a loop can be monitored for detector voltage, sensitivity voltage and threshold voltage using three analog Map Descriptors:
// Client Side Map Descriptors

|
Map_Descriptor_Name | ,Data_Array_Name | ,Data_Array_Offset | ,Function | ,Node_Name | ,Block_Number | ,Length | ,Msg_Type | ,Analog_Device | ,Scan_Interval |
CD_Analog_Volts1 | ,Analog_Volts | ,0 | ,Rdbc | ,Panel1 | ,1 | ,60 | ,Analog_Volts | ,0 | ,300s |
CD_Analog_Sens1 | ,Analog_Sense | ,0 | ,Rdbc | ,Panel1 | ,1 | ,60 | ,Analog_Sense | ,0 | ,300s |
CD_Analog_Thres1 | ,Analog_Thres | ,0 | ,Rdbc | ,Panel1 | ,1 | ,60 | ,Analog_Thres | ,0 | ,300s |

Use Float Data Arrays for the analog Map Descriptors to get the full analog value.
0 | : devices | Scan Interval on analog |
1 | : devices | pollers may not be shorter |
2 | : devices | than 300s to prevent |
3 | : devices | flooding the Foreign |
4 | : devices | Systems Interface. |
Note: If necessary, use more analog Map Descriptors with other Analog_Device numbers to poll other devices on the loop.
