GBerkheimer Posted June 12, 2018 Report Share Posted June 12, 2018 Im looking for an example of how to properly set up communications logic via EIP. I have 2 linear actuator controllers whose signal is a 2 byte word (16int) with 02T of 100 and T20 of 150. Ive tried two different setups that both seem to work fine for inputs setup 1: inputs/outputs on scanner nodes goes directly to a 16bit array, in ladder logic the EIP Get All has a fake 16bit int for Class, a fake 16bit int for instance, and the destination is the array I specified in the scanner node setup under protocols. Setup 2: inputs/outputs on scanner node settings page are 16ints I named raw data. The EIP Get All has the same 16int raw data signal as both the Class and Instance. The destination is basically the 16bit array from setup 1. As for outputs, its the same in reverse. In both cases, specific variables will enable the get all or set all functions at different times. I can read the current position and other bits just fine, and I can set/reset the output bits fine, but the output signal will not go out to the controllers. Even simple commands like setting the 16th bit to 1 in order to power up the servos will not work. The unitronics status number (8int) fluctuates between -6 and 48. Which is FA and FF in hex. there isn't a -6 on the EIP error page nor a 48 or FF. There isn't any reference to setting a class or instance in the manufacturers manuals for the actuators, controllers, and Ethernet settings. I have a big test file I wrote up yesterday, and a smaller test program I started this morning for just trying to work through my communication problems. I am attaching the smaller test program that just tries to accomplish turning the servos on and off, and I am attaching the Ethernet settings pdf for my PCON-CFA controllers. Any help would be appreciated. The two linear actuators are used to replace arbor presses that have been causing ergonomic inconveniences, and is my first project using unilogic. d ETHERNET_IP(ME0278-10D).pdf TESTPROGRAM_BEND.ulpr Quote Link to comment Share on other sites More sharing options...
