Post by joanm on Programmatically change the IP addresses of the Modbus TCP slave devices ^{CODESYS Forge talk (Post)}
Hello all, I am working in a project in which there are multiple Modbus TCP slaves. I need to be able to change the IP addresses of those devices from the HMI and I was planning to use the process depicted here: https://faq.codesys.com/display/CDSFAQ/Modbus+TCP+Slave%3A+Dynamic+Setting+of+the+IP+Address I can see the port number is what is used to specify which slave device we want to modify the IP address of. This said, can I freely set arbitrary port numbers to each device? I mean, can I set the first device to be at port 502, the second one at port 503... Any drawback or restriction? Is there any other way to reference to the device without having to change the port numbers? Thank you all in advance.

Post by davidbo on How to switch between dynamic IP address and dynamic? ^{CODESYS Forge talk (Post)}
I want to make an application with a UI for CODESYS Control for Raspberry Pi MC SL which make it possible to switch between dynamin and fixed IP address and to set the IP address. However I do not know whether that is possible?

Post by ph0010421 on Help with __SYSTEM.VAR_INFO ^{CODESYS Forge talk (Post)}
hi all I have a FB with IN/OUT variable. Inside the FB, I want to get the address of the IN/OUT variable. If I use __SYSTEM.VAR_INFO, I get the address of the FB copy rather than 'external' variable. VAR_IN_OUT MyVar: bool; END_VAR VAR Info: __SYSTEM.VAR_INFO; END_VAR Info := __VARINFO(MyVar); This give me the address of MyVar but I actually want the address of the variable passed to MyVar Any clues please?? thanks, ph

Post by martincapd on EWON ^{CODESYS Forge talk (Post)}
I have the same problem in that I can connect to the eWon and ping the controller IP Address, however I cant connect through CodeSys. I'm using Gateway-1 which is configured to use "IP-Address: localhost" and "Port: 1217". Rather than scanning the network for devices, I enter the IP Address of the device, codesys returns a "No Device is repsonding..." message. See attached. I'm wondering if the IP-Address used Gateway-1 should be "localhost" or the WAN/LAN IP of the eWon? Thanks for the help MC

Post by peterkcontrols on Copying 2 byte word to output ^{CODESYS Forge talk (Post)}
Hello. I am using codesys 3.5. I would like to know if it is possible to set a variable to an output without declaring in. I have defined a STRUCT and within this struct I have a Struct for inputs called I and a struct for outputs called O. I have declared a variable of the type of this Struct, I would like to set or alias the value in this variable to an input/output value of an IO block that has a module on the ethernet tree. Is it possible to copy the contents of %IW0 -> STRUCT.I ? The size of both of these is 2 bytes. I understand that I can declare a variable with the input like Input01 AT %IX0.0 : BOOL; However how can I make STRUCT.I.D00 AT %IX0.0? Is this possible? Thanks
