  1. Hi I'm trying to set up Modbus RTU communication between FX3U PLC and a weigh module. I would use the ADPRW command using 0X03 to read the 16 bit Holding Register but in the weigh module the Data Address/Holding Register of the value I want to get is 400047 - 400048. How to translate the value in 16 bit?   Thanks, Fabio
  2. Float Value FX2N Problem

    Dear All, I am facing a problem in FX2n, Infact i am making a totalizer from the flow. everything is fine. but client demands to add some totalizer value to start with totalizer.  the problem is that when i add 50000 value the value of registers stucks. although i am using 32bit float register along with DEADD command for Totalizer. the makes some steady at some place. i dont know why. but i give the totalizer 0 it works fine.  Any Solution regarding this will be help.    Value in the D72 = 0.0003
  3. Dear Engineerds,   My Master (non siemens) doesn't see the Holding Registers of the Slave (S7-1200) plc. However the Q coils are fine and all Diagnostics don't show errors. The Hardware: S7-1200 – CPU 1215C CM PtP – CB1241 RS485 (6ES7 241-1CH30-1XB0) - Half Duplex RS584   Firmware: Modbus_Comm_Load (V3.1) Modbus_Slave (V4.0)   I've tried with various DB, UDTs and manipulating HR_Start_offset parameter with no success. Could you advise what am I possibly missing? Modbus_Comm_Load_DB_Snapshot.xlsx Modbus_Slave_DB_Snapshot.xlsx

  5. HI everyone ,  i will be very glad if anyone helps me to clear the doubt . I am using MX component version of 4 to connect with my CCLINK J61BT11N   Board. Is there a way to read group of registers from the CC-LINK . for example, if i want to read from D0 to D5  or write D0 to D5.  is there any function  in MX component which helps to read the group of registers? I use MItshubi PLC .
  6. Hello , I'm using Allen Bradley Micro850 - 2080-LC50-24QWB PLC. I downloaded a program to that PLC by CCW. My customer wants to build an application (like a GUI) on a PC which ables to read and write the I/O's , therefore he needs me to send him the registers of the I/O's that i have used in the program. so i woule like to know the register for every tag or I/O. where can i get that information from? for example , i would like to read : _IO_EM_DI_00 , how could i know what this tag's modbus register is? thanks in advance.

    Hello all ... i am a new plc user.. i am using D500 for taking value as it is a latched register.  i am taking value for a flow meter. i have two questions. 1. how totalizer is calculated from flow rate as my flow rate is in m3/h. 2. the value of register is gone upto 32000 approximately... i want that this value to go on.. i mean how 32 bit register is declared in plc .. a
  8. We have Q06UDEHCPU PLC.   We require to attain 1k of file registers in standard Ram. Please find our settings attached - PLC Parameter.png; When we try to down the register file – we attain the following error; “Failed to access standard Ram” error message (attached - Downloading Error.png); The program is very small – and thus we have plenty of space as well.
  9. Compare not working

    We have this logic (on a CP1E) the desired outcome is as follows: When a bad part is detected, force the operator to index the machine 6 times, using a holding register to prevent a power cycle from resetting the count. once 6 cycles are recorded output that the bad parts are removed AND reset the count to zero.   What has actually happened so far: the count has gone to 6 and not reset. I have used CX Programmer to set the H0 value to zero but the compare still says it's equal (to 6)   I have read everything i can get my hands on regarding holding registers and compare functions and i can't see what is wrong. I have no formal training on this so i'm sure it's something simple. can anyone point me in the right direction?   Thanks guys    
  10. Hi All, I'm testing Cx-supervisor communication with ODT Micropower PMAC controller on modbusTCP. I'm able to establish the communication using ModbusTCP driver with cx-supervisor. But, data I'm getting in is Low word first, so not able to convert properly. If anybody has tried any other option/script for this issue? I did not found any setting in Cx-Supervisor as in Kepserver, shown in attachment below: How can we swap the registers read as a 32 bit word from controller? Thank you.
  11. DOPSOFT HELP

    I'm using HMI DOP-B03E211 and its connected to DVP12SE11R PLC . In the DOPSOFT i would like to know how i could create a list of the whole indications in the system - once a specific indication is on, the list shows the name of that alert ( " system alarm failure") when its off the list doesnt show it .  there are indications in a bit form ('1' or '0') and in a word form (temperature indication). how can i create a list that combines whole system indications including bit indications and word indications?   thanks.
