Title: CLX Msg Instruction with BRX Explicit Msg Server
Post by: ATU on July 17, 2019, 12:45:57 PM

Trying to communicate using the Explicit Msg Server using an AB CLX L24 Brick
BRX Settings
IP  128.168.0.250
mask 255.255.255.0

TCP Port 44818
BLOCK 1
ENABLE READS
Enable Writes
Element TYpe N
Start 100
Element Count 10

CLX
IP 128.168.0.50
MASK: 255.255.255.0


Msg Instruction
CIP Generic
Set Attribute Single
Instance 101
class 4
attribute 3
PATH 2,168.0.250

Source - Int array (10)
Source length 20 bytes


ERROR CODE: 16#0013     CONFIGURATION data size too short

I think it is connecting because we originally had the path wrong and got a timeout, but now we get this error.

We have tried everything, anyone have an idea what is wrong?

We are going to try this with an empty program running in the BRX.

It was an RS5000  issue. We had the array listed as the source instead of the FIRST element of the array in the AB message instruction. It allows you do this without any syntax error.  We are processing a TCP stream from a PC and connected to a CLX receiving MSG instructions. Sending all the data to the Modbus Server on the POM. The BRX makes a very inexpensive custom protocol converter.
