McQuay:#22 Err. Illegal

Check configuration file, a Node_ID is out of range. 11

 

 

Node_ID [%d] - Set to 1

 

 

 

 

 

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

 

 

requires non-critical update.

 

 

the Node_ID as follows. Divide the old Node_ID by 256. Set the

 

 

Read Manual.

 

 

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

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

 

 

Node_ID/Route

polls to a node. The driver guesses that the reason is that the

 

 

Response=NAK. Read Manual.

Node_ID/route or password has been incorrectly specified in the

 

 

Maybe password or Node_ID

configuration file. Verify these settings. The message is printed once

 

 

 

and suppressed for subsequent occurrences. Refer to Appendix C.2

 

 

 

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

 

 

responded with a NAK.

 

 

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.

 

11Correct the configuration by editing the CSV file and downloading it to the FieldServer, then reset the FieldServer for the changes to take effect.
