Appendix C. Troubleshooting Tips
Appendix C.1. ProducerID with FieldServer device as Producer
During testing it has been observed that a 90-30 PLC required that the ge_ProducerID
parameter was set to the same value as the IP Address of the FieldServer.
Appendix C.2. Produced Time Stamp
The GE-EGD (Ethernet Global Data) driver always set the timestamp of produced data to
the time of the Field Server Device. The nanoseconds portion of the time stamp is always
set to zero.
Appendix C.3. Status Values
The status of the EGD Exchange may be monitored in the GE PLC. The status value is well
documented in GFK-1541 Chapter 4.4. During testing, using the Field Server device as a
producer and the GE Device as a consumer the following status values were observed.
0 -> The exchange had never been consumed
1 -> Normal
4 -> Length of produced and consumed exchange not equal - Different messages with the
same exchange ID.
6. -> Timeout.
