Error Message Action
McQuay:#22 Err. Illegal
Node_ID [%d] - Set to 1
Check configuration file, a Node_ID is out of range.
11
McQuay:#23 FYI. Config
requires non-critical update.
Read Manual.
If the Node_ID is greater than 255 then this message is printed. In
versions of the driver prior to 1.02 this was permitted and these
configurations will operate correctly. In versions since 1.02a the route
parameter is used to provide the routing device’s address. Convert
the Node_ID as follows. Divide the old Node_ID by 256. Set the
Node_ID equal to remainder and set the route equal to the quotient.
Example; Old Node_ID = 834. 834 div 256 = 3 remainder 66.
Therefore Route=3 and Node_ID=66.
McQuay:#24 Err. Illegal
Node_ID/Route
If the Node_ID is > 255 and the Route is specified too then this error
is printed. The Node_ID should be a number in the range 0 to
255.Error! Bookmark not defined.
McQuay:#25 Err. Max Len=1
when Bytes_Per_Field > 1.
MD=%s.
The length parameter must be set to 1 when a Map Descriptor has
the Bytes_Per_Field parameter specified
10
McQuay:#26 Err. Max
Bytes_Per_Field=4. MD=%s.
Legal values for the Bytes_Per_Field parameter are whole numbers
in the range 1 to 4 inclusive.

McQuay:#27* Err.
Response=NAK. Read Manual.
Maybe password or Node_ID
This message is printed if a NAK response is received in the first few
polls to a node. The driver guesses that the reason is that the
Node_ID/route or password has been incorrectly specified in the
configuration file. Verify these settings. The message is printed once
and suppressed for subsequent occurrences. Refer to Appendix C.2
McQuay:#28* Err. Device
responded with a NAK.
The message is printed and then suppressed for subsequent
occurrences, but the NAK stat is incremented for each occurrence.
The driver is reporting that the McQuay device responded with a NAK
under different circumstances from msg#27 which is printed if the
NAK is received during the first few polls. The message indicates that
the McQuay device could not respond. If the NAK's are occasional,
assume that noise has corrupted an occasional message. If they
occur frequently assume a systematic or connection error. Refer to
Error! Reference source not found. and Appendix C.2.

Correct the configuration by editing the CSV file and downloading it to the FieldServer, then reset the
FieldServer for the changes to take effect.
