Appendix A.2. Interpreting Panel Error Messages
A NAK is sent by the panel when it is unable to respond to a message. The format will be as follows:
T02>
T02>
The following table lists the reason for the failure and the suggested corrective action. Note that the messages are generated by the panel, not the FieldServer.
Reason # | Error | Corrective Action | |
Reason 1 | Checksum or Parity | Ensure connection baudrate, start, stopbits and parity match the panel's | |
fail | settings | ||
| |||
|
|
| |
Reason 2 | Receive buffer full | Increase scan interval on the poller Map Descriptor. | |
|
|
| |
Reason 3 | Syntax Error | Check integrity of physical connection to panel, route cables away from | |
electromagnetic sources that can generate noise. | |||
|

Reason 4 | Unrecognized | Replace hardware? | |

Appendix A.3. Obtaining Point Addresses from the panel report
In order to configure the FieldServer to capture data from the Panel, the point addresses being used in the panel need to be identified. The Panel report that can be printed out from the panel can be used for this purpose, but matching the Report parameters with the FieldServer configuration parameters is not a trivial exercise. The following notes should assist in identifying the addresses needed for FieldServer configuration
•The preamble to the report is not relevant to the FieldServer Driver.
•The first Module can be identified by the title NET Address =1. This corresponds to FieldServer’s “Block 1”.
•The Module Subaddress corresponds to individual points in the Block Array.
This information is depicted in the following file extract:
Corresponds to Block Number 1
NET ADDR: 1 ==> | Page: 5 |
===============================================================================
Corresponds to Block Array point 1
Module Subaddress | > 1 |
