I guess one fuse will protect it anyways. Got the bussman book, will look through it soon. Thanks for the info.

I need to load values to special registers in existing program but not sure how to do it. These values are there now but some need to be changed and I don't see MOV command in the program which would load them so I guess it needs to be done in GX somehow just don't know where to start.

I have never used Mitsubishi CC-Link so it seems a bit confusing. As far as I understand you use TO/FROM instructions to communicate and the memory used for data exchange is on Master so if master puts out some bit value to location H167 the remote station would read that value using FROM instruction from location H167 is that correct? And I guess the same goes for the other way around. Looking through existing program I see the following in the (D) field of FROM or TO instruction: K4M532, what does the K4 mean? I have also seen K2, K1 and then M..., I guess the M is the bit where you want the data to be read from or stored to but don't know what the rest is there for. So lets say we want to communicate M268 from the Master rack position H14 to Remote station rack position H10 and store it in M502, The instruction for master would be: TO H14 H167 K4M268 K1 The instruction for remote would be: FROM H10 H167 K4M502 K1 Am I getting it right? Thanks.

Guys, Thanks for great info. Smahon, So if I want to transfer only 1 bit, then I don't need the Kx at all in front of M268, just M268 alone? And one more thing just to clarify, if I changed the K1 at the end of TO command in my example to K2 this would mean that 32 bits will get transfered (M268 to M299) and in fact will do the same as specifying K8M268 K1?

I am trying to do jump to label in RSLogix 500 for the MicroLogix 1000 PLC. Not sure what I am doing wrong but basically I placed the LBL as first item on rung and called it "Move_Again" in the small window that showed up over the LBL symbol. Did exactly same with JMP except that it was placed at the end of the rung. When I verify I get the following two messages: Rung 6 Ins 1: Error: Parsed entry as symbol: Move_Again does not have an address assigned in database! Rung 10 Ins 5: Error: Parsed entry as symbol: Move_Again does not have an address assigned in database! Does anyone know what am I missing? Does anyone know the www address for rslogix 500 command manual? Found one for rslogix 5000 but don't know how much difference there would be between these two.

I am trying to position with Q00J processor and QD75MH1. I send the following to the motion module: TO H0 K2000 K256 TO H0 K1550 K1 K1 DTO HO K2006 2100000 move to 210deg SET Y10 I have set the units to degrees in GX Configurator When I try to execute the above I get error 108 and the servo does not move at all. Can anyone shed some light what am I doing wrong? I send the PLC ready to the module and receive Servo rdy signal back at the beginning of the program.

Is there timer which would go to set value, set T coil for a scan or so then reset itself back to 0 and do the timing again? I am basically trying to flash light using regular time interval.

Thanks everyone, I used the SM413 which is 2 sec. internal timer. There is so much stuff in Mitsi it is hard to grasp at the beginning and the manuals are very bulky and sometimes info in them is hard to find, especially when one does not know the particular function exists. Thanks a lot.

I have to store some setup data that would be entered via touch screen and I wonder where can it be stored to be preserved during power off since I don't want to have it replaced every time the PLC is powered up. I looked through the manuals but am not able to figure out how to do it.

Is there latch reset on the Q00J PLC as well? I don't see one just by looking at it.

Do I have to create them while running my software or can I create them somwhere in setup/PLC parameters?
