Post by tvm on SEND_RECV_MSG function block on Schneider Machine Expert ^{CODESYS Forge talk (Post)}
Anyone else using the SEND_RECV_MSG function block for RS-485 communication on Schneider Machine Expert? I have had ongoing issues with it for several years, which Schneider tech support is aware of, but hasn't been able to fix. The latest version of Machine Expert (v2.2) appears to have broken some of the functionality altogether. I'd be interested in hearing from anyone else using this platform for serial communication.

This works for me in Schneider Machine Expert 2.2, which is based on Codesys 3.5.19. It did not work in Machine Expert 2.1, which was based on Codesys 3.5.16. METHOD PUBLIC Method1 : INT VAR_INPUT TestVar: INT:= 5; END_VAR Method1:= TestVar; PROGRAM SR_Main VAR TestFB: TEST_FB; Var1: INT; END_VAR Var1:= TestFB.Method1();

Post by tvm on Web Client (HMI) Disconnects from Webvisu (Weidmuller u-OS) ^{CODESYS Forge talk (Post)}
ok, that's different than our issue then. We're using Schneider Electric M262 PLCs, and we've had it where certain web browsers cause the web server to only allow https connections, but it's not recoverable with a refresh. It usually requires a power cycle or even a full firmware flash. Your issue might have more to do with the timing. I don't know if it helps you, but we normally run our visu task at 200mS, with an update rate of 200mS. Seems to work. I went through this: https://faq.codesys.com/pages/viewpage.action?pageId=112525371 but it really seems like trial and error.

Post by user3000 on Can't find an Extended Pulse Timer (TP and LTP) ^{CODESYS Forge talk (Post)}
I came up with an FBD that seems to be working, although it may not be a true Retriggerable Pulse timer. There may be some delay associated with the two MOVE functions and ADD function I incorporated. I'd be interested if anyone is able to come up with something cleaner. I am surprised that this is not a built-in function block of the CodeSYS library. This is a common feature of multi-function timer relays. I also attached a page from the cut sheet of a Schneider relay that shows 10 timing functions. Looks like the CodeSYS library has built-in function blocks for only 3 of the 10.

Hallo Forum das ist mein erster Post bei euch also bitte seit nachsichtig :) ich habe mir den: USB zu CAN Konverter Kable for Raspberry Pi4/Pi3B+/Pi3/Pi Zero(W)/Jetson Nano/Tinker Board and Any Single Board Computer Support Windows Linux and Mac OS (USB2CAN-C) Gekauft da er in Linux arbeiten soll dachte ich man kann den so in codesys einbinden da es auf einen Rasperry Pi lauft. Erkannt wird der Adapter als Bus 001 Device 004: ID 1d50:606f OpenMoko, Inc. Geschwister Schneider CAN adapter Wie bekomme ich den in Codesys mit einen Rasperry pi eingebunden. (Im Internet habe ich nichts gefunden.) ich bedanke mich. euer Martin

Post by paulorb on STRUCT AT %MW1000 ^{CODESYS Forge talk (Post)}
Hi I am trying to use STRUCT to parse commands from Modbus/TCP, Modbus client will fill the bytes related to a specific command (type, parameters), then PLC (Codesys) will access the command parameters. A STRUCT will simplify a lot the process of parsing the data, so I don't need to parse byte per byte, address will be mapped to a struct and I can use it for parsing the data. From what I understood, the compiler does not allow me to specify the location of the struct for a %MW register. VAR_COMMAND AT %MW1002: structGenericModbusCommand; This will throw: Bad declaration, use '%ML' for 'structGenericModbusCommand' variable But If I change it to %ML, when you go online you see that it is actually allocating the struct in another memory address. When we go online, on GVL we can see: VAR_COMMAND. structGenericModbusCommand %ML1002 commandType COMMANDTYPE %MB8016 ... %MB8020 I am not specifying a pointer or a reference it is a struct type, why is it mapping to a %MW location (random one). How can I control where it is mapping to? I need a consistent way to map STRUCT to specific modbus address. Is it possible? Thanks, Paulo Note I am using a Codesys OEM: Schneider Machine Expert Logic Builder (M241)
