RSLogix 5000 & Solartron Orbit3

11.1.2.2.Implicit Messaging These types of messages are used to read or write a ‘block’ of data.

Note: The Orbit Network ‘Readings’ are available in the ‘read’ block of data, and the data contained within a reply to this type of message will contain a set of Synchronised Readings from the Orbit Modules, where Synchronised means all the readings were sampled within a 256uS window of each other.

The Implicit messaging settings required to communicate with the PIM are as follows:
- Unicast Connection Type.
Read Assembly Instance 100
Write Assembly Instance 150
Configuration Assembly Instance 3

For details of the Read-able block using implicit messaging, please see the file “PIM_EthernetIP_IF_CyclicRead.csv”, which includes details of total block size, parameter types as well as byte offsets in the response ‘block’ of data.
For details of the Writable block using implicit messaging, please see the file “PIM_EthernetIP_IF_CyclicWrite.csv” , which includes details of total block size, parameter types as well as byte offsets in the ‘block’ of data.

From the manual:

Looks like you would want to set up a Generic Ethernet module. The values in bold would get plugged in there. The mentioned CSV file should tell you the size for each block and what they are for. you may also want to check if you need things in DINT, INT, or SINT to match up with the layout of the blocks.

Purely a guess, based on the manual and csv files.

Hi Johan,

The PIM module looks like what you need.

As you just discovered, Ethernet is not the same as Ethernet I/P.

The ETHIM may still be good for monitoring from a PC or SCADA. It'll give you interesting options to branch out.
