  1. Looking for Socket TCP/IP communications program examples for Mitsubishi PLC iQ-R R04CPU using GX Works3, to compliment the Mitsubishi Ethernet manual Socket commands instructions. Unfortunately, the manual is missing real application ladder logic illustration examples of these commands. For example, the Socket Open Connection command, does not describe in what order or format to enter the IP Address.   For example, to enter IP Address 192.168.1.100, does the most significant octet 192 is entered or stored first in the lowest memory storage register (Big Endian format) or does the least significant octet 100 is entered or stored first in the lowest memory storage register (Little Endian format)? I am trying to write a simple Socket TCP/IP communications command that will write about four registers from an existing Mitsubishi PLC R04CPU (Socket Client) to an Allen Bradley PLC ControlLogix (Socket Server). .

    Hello, I am working with e5cc-t programs, for heating application. I need to find a way, to start program, when temperature reaches set-point of first (no. 0) segment. I think that, there should be some kind of setting, but i cant found it.. I've done this with PLC, but this is not an solution for this application. in conclusion: After program starts, it has to reach set point temp, and then hold temperature for certain time.

  6. I am trying to get the communication going between EZ3 EZAutomation Panel HMI and Omron NJ501-1300 PLC. I am currently using Modbus TCP/IP as a protocol. Has anybody figured out a way to do that? Or is there a better way to do this communication between HMI and PLC ? Right now I am using MTCP_Client_Connect function block to connect with HMI but it dont seem to be working. The IP address is correct along with Port no. I am still fuzzy about the Station address of NJ and the function code of the NJ for Modbus purposes. If anybody could help me out I would really appreciate it.

  11. Beckhoff PLC Counter

    Hi everyone, I need some help with my PLC programming. I am currently using a twincat 2 software and a Beckhoff CX 8090. Basically, the gist of my program is to send and receive data and datalog the input data received from the sensors and timestamp the received data for every 1 second. I want to create a boot up counter where it will count the number of times my data logging program has restarted(if it did). This boot up counter serves as a health monitoring check to ensure that my program is running perfectly and thus, not restarting randomly when it shouldn't. I am more familiar with structured text so if you have a solution, kindly post it in structured text form. Your help would be greatly appreciated. Best regards, DeadPool

  20. 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
  21. I just commissioned a system utilizing 3 1756-IRT8I TC Analog Input Modules. It was soon discovered that there were sags in the order to 2 -10 % in the inputs across all channels. These sags occurred in all three modules but at different times but were occurring more or less on ~4-6 hour intervals. There are two CJC inputs (Cold Junction Compensation) and it was discovered that one CJC value also sagged while the other one remained constant through the sags. Tech Support had no information about the issue, but eventually found that there was a thus far unannounced firmware update, that was made available. The problem modules all had FW Version 1.013 and the Update Version as of Mid Oct, 2015 is Version 1.014. Following the FW update, the sags are no longer being seen. Bob A.

  23. 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
