Hi I am trying to write some code to control an Agilent DACU from an SLC/500. I have the code to setup the DACU and read the results. The problem is with how it has to be done. The DACU could have up to 120 channels to get readings from. I can only do 5 channels at a time due to buffer length restraints. Here is how it should work Start Loop Set up channels 101-105 Read channels 101-105 Store readings Setup channels 106-110 Read channels 106-110 Store readings Setup channels 111-115 Read channels 111-115 Store readings .... End Loop The current issue seems to be that the code is starting on the second group of channels, before the 1st group is finished. This causes the DACU to stop working all together I have attached the RSS file in question from RSLogix 500. Any help would be greatly appreciated. I have been programming various systems for 20 years, but this is my first time with a PLC and it is kicking my ***. Thanks Mark THIS_ONE_WORKS_VERSION_4.zip

To get things working on my Windows 7 x64 Ultimate machine I did the following: RSLinx Classic 2.52 Run the main program using XP SP2 compatibility mode I know I did some tricks for RS Logix 500 as well, but I don't remember what. Something to do with stopping a service to enable it to start Hope this helps in some small way
