I was wondering if the powers that be would be willing to create categories for some of the rest of Omron's line, such as AMR's, Sysmac usage for PLC's, etc. I first looked at this forum when our Omron rep was visiting and we were discussing tech support for our new AMR and associated PLC's. He mentioned that Omron had this forum, but we were both surprised when we saw the limited scope of the group. I've been getting help directly from the Omron applications engineers, but they've lost a couple of the local people and a lot of my questions are really basic PLC programming issues that are probably better answered in a forum setting (if I can't get an answer from googling it). I have had some success on the MrPLC forum, as they do have a specific Sysmac/NJ.NX category.

Another simple problem I believe . . . I'm turning on a motor, keeping it on for a specified time, then shutting it off. The thing is, I have to use a function block to turn on the motor (ARCL connection with mobile robot). So, I'm setting variables MotorOn to activate the timer once the initial function block is complete , and Timer_done to activate the function block to turn off the motor. This works fine, unless I try to stop the motor before the timer has expired, by turning off the Start_motor switch. In that case, Timer_done never becomes True, so the motor continues indefinitely. Seems like there should be a fairly simple way to activate the Motor_Off function block when the Start_motor switch is turned off.

I at least was able to take Omron's Sysmac training class, but it was a lot to take in within a 3-day period for an old guy like me with no real PLC background.

I see this question is a couple weeks old, so you've probably figured things out already . . . I'm a newbie also - trying to get up to speed with an NX1P2 and an NX102 to communicate with and control a mobile robot. My understanding of the variable definition part of the program is that this is basically handled behind the scenes based on the variable definitions created in the Variables window, within the I/O map, or on-the-fly in the program. So far I've managed to make some lights go on and off on a breadboard setup with the NX1P2, and turn a couple conveyors on and off with the NX102. Struggling a bit to get the NX102 to talk to the LD250 robot so far.
