General Information
The driver continually monitors received data and stores values. Up to 8 device addresses may be entered for monitoring.
Level and temperature values are converted from ASCII to real numbers, eliminating the need to account for varying decimal places. Strings containing multiple values are sorted appropriately.
If an invalid address is present, the driver defaults to address 192 in ADD1. [g3-mtsddamonitor | Word]
Command Specifics
ADD
Eight array locations are available for assigning device addresses. Duplicate addresses are not permitted. The array position determines where corresponding data is stored. [g3-mtsddamonitor | Word]
PROD, INTF, TAVG
Values are stored in array positions corresponding to their associated address in ADD (e.g., PROD3 corresponds to ADD3). [g3-mtsddamonitor | Word]
TIDT
Each address provides 5 values:
- TIDT1–TIDT5 → ADD1
- TIDT6–TIDT10 → ADD2
- TIDT11–TIDT15 → ADD3
(and so on) [g3-mtsddamonitor | Word]
CADD
Changes a unit’s address from its current value in ADD to a new value.
Returns to 0 once the command is sent. [g3-mtsddamonitor | Word]
SGEN
Used to examine unsupported or unidentified data strings.
- Must be configured as String
- Encoding: Packed High-to-Low
- Element: 0
- Displays incoming string (without checksum/ETX)
- Writing any value clears the string [g3-mtsddamonitor | Word]
COMM
Contains 5 counters corresponding to PROD, INTF, TAVG, TIDT, and SGEN.
Each increments (0–255) when new data is received, indicating active updates. [g3-mtsddamonitor | Word]
