Has anyone ever communicated between a MicroLogix 1100 and ABB ACS800 drive over Ethernet? Possibly using explicit messaging, I don’t believe the ML1100 supports Ethernet I/P. |

The "MicroLogix 1100 controllers support CIP explicit messaging (message exchange). MicroLogix 1100 controllers do not support Ethernet I/O master capability through CIP implicit messaging (real-time I/O messaging).” http://literature.rockwellautomation.com/idc/groups/literature/documents/um/1763-um001_-en-p.pdf The MicroLogix 1100 (OS Series B only) supports a MSG instruction with CIP Generic Target Device. From the setup screen you can configure Class, Instance, Attribute, etc. for the Target Device (in this case the ABB ACS800). The ABB ACS800 Ethernet Adapter Module fully supports the Ethernet I/P communication protocol. The user manual provides the necessary Class, Instance, Attribute information for the drive parameters that the user would need to read/write. http://library.abb.com/global/scot/scot201.nsf/veritydisplay/b3b3c13dcead1c3ec12572aa002977cc/$File/en_RETA_01_um_d.pdf AB technote 52205 also describes how to control a PowerFlex Drive on EtherNet I/P using explicit messaging with the use of PCCC emulated block transfer using NFiles. This is well documented and sample PLC code is provided. This Technote is not applicable to the ACS800. |
