  2. 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

  5. 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

  8. 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?
