Typically we interface to dozens of third-party devices that have Ethernet/IP capability WITH appropriate documentation to set up a GENERIC ETHERNET module with these variables:
Byte Format – SINT, INT, DINT
Input Instance and Size
Output Instance and Size
Config Instance and Size
With the above information, the third party device is established with IMPLICIT cyclical polling and automatic transfer in/out data to our PAC data table.
What we CAN’T do: Get the most simplistic GROSS weight data from an Avery ZM303
We are NOT weighing trucks. We have about 10 load cells and 10 ZM303 monitoring a chemical operation, and are merely trying to read the GROSS weight continuously.
We have Z-Tools software and can connect to the instrument, and see the Ethernet/IP configuration area, but Avery has little or no instructions. It is clear that the instrument MUST be configured to output variables, but it is not documented how to do such.
Calling Avery, they refer us to our distributor. Although we spent thousands of dollars with the distributor, they have no Ethernet/IP experience, and can offer no help.
There are a few existing threads on PLCs.Net regarding this subject, but they are dated and have not led us to a solution.
We prefer to NOT do Explicit Messaging. We prefer NOT to do any socket based TCP/IP programming. The ZM303 is advertised as “Ethernet/IP” and should be capable of IMPLICIT cyclical data transfer.
If anyone has had recent success, we would appreciate tips, and tricks.
Thank you
