Greetings to all

I have a problem when trying to download a program from a FX1S-30MT PLC. I am using a SC-09 USB cable. The software i am using is GX Developer 8. When trying to download the MAIN program the screen in the attachment appears. I tested the download from another PLC of same model and have no problems, therefore the cable is ok, and the laptop is ok. When downloading of the parameters and comments does not give error, just when trying to download MAIN. Also I tested connection with Test Connection button and says communication is ok. Anyone who can help? I have a doubt, how can i see the communication parameters on the PLC side? Thanks a lot

Hello! I am working with RSLogix5000 software and writing the program. Very often I need to download the program to the CPU and of course it writes all program at the same time. This downloading makes problem to me, because I loose parametrizised data from the CPU, downloading will always overwrite default values of the tags. Some parameters are written from the panel and I want to keep these parameters allthougt I am downloading new program. How should I handle this? Some tags can be overwriten, some not.

Hello, First of all, Hello to all members. Im From Portugal. I trying to help my dad. I Have a Omron CJ1M-CPU11 with a program running that works fine... Now i need to transfer this program to a CJ1M-CPU13. I started to download from CJ1M-CPU11 to a file... them im running the Cx-programer on the CJ1M-CPU13, connection its ok, but when i try to transfer i get this error : The connect PLC type : CJ1M-CPU11 The Project PLC type : CJ1M-CPU13 Its possible to convert ? Please Help. Please view in attached file. Thanks

Hello: I'm not sure how to go about creating the structure of this program, would like some ideas/help. I have a program that checks/reads 8 analog inputs and compares each input against 4 different settings, if the value is outside any of these settings the program runs a subroutine to send out an email for (Alarm/Event) notification for that particular input. The way the program is structured now is that it reads analog input 0 first and checks against the settings if the reading is not in range it will call a subroutine to send out email for that sensor(analog AI:0.0) then it will return and read for Analog input #1 and check reading and if it needs to it will call another subroutine to send out email for that sensor(analog AI:0.1) and so forth. What I need to add, is a way to count how many times a sensor(input) has sent the alarm email because I want to limit this to 5 notifications after that, stop sending emails. Now this has to be done for each sensor(input).(Note: I would also like to have a timer involved so that it will only send emails about every 15 minutes for 5 counts.) I need this because the plc will send out emails until the error for the sensor has been corrected, this could take a few hours and if I don't have some sort of control, that would result in 1000's of emails being sent and world probably get shut down for spamming. Would like some ideas on how I should go about this. I am using a micrologix 1100 and rslogix 500 software. Thanks

Do I need to write the "Program Loop" into the ladder or will the complete program start over once it has hit the "END RUNG"??? Micrologix 1100, programming with the RSLogix500. Thanks

We have a couple Mitsubishi FX2c-96MT 's running a Laser engraver and one of them appears to have a faulty card or connections on the card. we picked up a couple spares one is a FX2C-96MT and the other is FX2c-96MT-ess. Is there really a difference between these? I see on the old PLC the middle card says ess on it already? we need to "harvest" the current plc program before swapping into the new unit. we picked up one of the cheapie pc connection kits which doesn't look like it is right and don't want to connect it and burn something out. IT has a rs232 on one end than a male 25-pin connector with a second cord that goes from female 25-pin to the mini-DIN connector. Neither of the FX2c-96MT plc's have a mini-din connection as i read online everywhere. there is a 25-pin connector on the top next to the FX2c-96MT label. is this the programming port? I would have assumed the programming port would either be the one covered up by the battery cover or the little one on the end with a 3/8 x 1" cover. I am assuming thae, with no instructions for much of anything. Thanks for all and any help in this matter t we should be able to use an older laptop running winXP for this? i downloaded GX developer and will install it on the xp laptop as soon as we are able to be sure of a cable that will be safe and not damage anything. If this cable we purchased will not work, could someone send a link for instructions to fabricate one? I see several in a gogle search, but they are all different and we want to make sure we do this safely as the program on the PLC is apparently NOT backed up anywhere, and the people who set it up years ago are long gon Paul

Hey, this may be an obvious question, but here goes: I have a CompactLogix L36ERM running RL5000 controlling one of our lead die cast machines. When I make a change to the program offline and need to download I always go and shut the machine down for safety reasons before downloading. One of our techs stopped the machine but left the control power and hydraulic pump on while downloading (something we are not supposed to do) when he finished downloading he switched it back to run mode and the machine closed on it's own and started right back up. This is a safety concern to me. We have a "close enable" tag that is true when all necessary conditions are met, and gets latched on when the machine is running in full auto. Before he downloaded the machine was at idle, meaning that the only way to close the machine would be to press the two dead-man switches to start the process. But, when he downloaded it started up automatically. Now I know the reason why is when the program was last saved, the "close enable" tag had a value of 1, it was latched on, so it bypassed the dead-man switches. A quick fix would be to save the program with that tag un-latched so that it can't start up on it's own after downloading. But, in case somebody saves the program while the machine is running and with that tag latched on, I need a better solution. Is there any tag or bit that goes true when a program is downloaded or when the mode of the PLC is switched from run to download to run? I want to manipulate that tag so that when I download it un-latches the "close enable" tag. I'm sure there is a way to do it, I'm just not even really sure what to search for in the online help. Any help is greatly appreciated. Thanks Howard

I am writing a new program for a MicroLogix 1500 LRP Series C. When I verify the project I get the following errors: Program error ERROR: Attempted to set more IO data than has been allocated Program error ERROR: Incorrect Output Force File Size The IO Configuration should be correct because I had the software "Read IO Config". I don't see any unverified rungs. My software is RSLogix 500 Version 9.00.00 (CPR 9) Does anyone have a solution?

Hello Everyone, I am new to ladder logic, and trying to understand flow of below attached ladder logic- How does the program flow ? Does PT4601_I in rung 3 waits for rung 2 to complete inorder to consider updated value of PT4601_I or it consider PT4601_I default value and runs simultaneously with rung 2 ? Thank you in advacne
