2.3.4 Using Result Codes in the Program
After P125 has executed, check the result codes. If the result code is greater
than or equal to two, execute P125 again. Recheck the result code on the next
pass of the program table. Example Algorithm:
If time to write data
Write data to Final Storage
Execute P125
Use P89 to determine if result code >= 2
If true execute P125
end (P95)
2.3.5 When to Execute P125
Usually P125 is only executed after data has been written to final storage.
While this is not critical, it makes more sense. When P125 sends new data to
the PTT, all data in the PTT is replaced. If P125 is executed when there is no
new data in final storage, P125 returns a result code of 1. Existing data is not
removed from the PTT.
TABLE 2-1. P125 Result Codes
Result Code
Code Meaning
0
Normal response, transmitter on line and data packet received
1
No new data in datalogger active final storage area
2
No response from the transmitter, transmitter may be
transmitting
3
Improper response from transmitter
4
Data packet not properly received by transmitter
5
Transmitter timed out before data packet was received
6
Datalogger serial port not available, probably in use by another
device
