Post by thieulam on Codesys access to DICTIONARY OBJECTS of ethercat (CoE ) Servo Drive ^{CODESYS Forge talk (Post)}
Hello to all! How can I read or write, via my main code (ST), to the registers present in the DO of my ethercat CoE servo drive? These objects appear in the list of the INITIALIZATION page, and from here I can only access them at startup. How do I access it in run time from my main PLC_PROGRAM?

Get a different sensor that is 0-10V and 0-350 Bar. There is nothing you can reasonably do to boost the range of the sensor, and the PLC will only ever be 0-10V. Take away is to always be careful to match the sensor and PLC input ranges in the future.

Post by jens on Modbus tcp - channel ^{CODESYS Forge talk (Post)}
Help wanted This is the first time i'm doing a Modbus Tcp project. I have some VLT with a extension module MCA-122. i'm currently unable to write to the VLT slave, but i can read from status word parameter=1603 and address := 16029 where the address is calculated from parameter is ((id x 10)-1). in the manual the functions that are supported are 3 hex, 6 hex, 10 hex, b hex and 11 hex. read holdin registers, write single register, write multiple registers, get comm. event counter, report slave id. i'm only using the Modbus Slave Channel is this wrong when trying to write to the vlt ?

Post by abinvest579 on TCP Client ^{CODESYS Forge talk (Post)}
Hi All, I am using codesys based plc to read and control magna power DC supply over LXI protocol using SCPI command. To connect device required socket programming for that i am using Net base service library function block TCP_Client to establish connection over TCP/IP , TCP_Write to write SCPI commands and TCP_Read to read data from Magna power DC supply. I have attached screenshot for logic developed. I am able to connect and write commands to device but i not receiving any information from device. For writing Commands i also tried various end of line character like \n,<nl>, A, D, 10, 13, 0x0A, 0x0D but not received any status from device. For testing purpose i am using simple command '*IDN?' to read data. Also if tried to check on hercules software what data actually plc read, first it read correct data after that is read wrong data as see in screen shot. 'Hello World' was correct read and after that Codesys in replaced with 'Codesysorld' that is not correct way. Same issue also appeared for send data. Any one have face same issue how i can read data directly from device correctly and send data please suggest solution on this.</nl>

Post by mgengler on Recipe Manager - Not Creating Recipe Files ^{CODESYS Forge talk (Post)}
Recipe Manager will load windows explorer view and allow file name to be typed in or existing file selected but will not create a new file or overwrite an existing. Will not create a file in the default folder or even a defined folder like "c:\recipes\" although it does properly navigate to that folder location. I made sure the folder is not read-only. Can't figure out what is missing...

Post by ivanh on kepware minimun privilege ^{CODESYS Forge talk (Post)}
Hello everyone, I’m integrating Codesys with Kepserver using the Kepware driver for Codesys, and I need to configure a user account with the minimum necessary privileges to read and write to the tags on the PLC, without using the internal OPC UA server of Codesys. However, despite not assigning the Modify permission, Kepware still allows writing to the tags. What are the minimum required permissions to ensure that writing is only allowed when necessary, and how can I prevent other permissions from being overridden? Any guidance would be greatly appreciated.
