Post by nico01 on Integer with comma in visualization ^{CODESYS Forge talk (Post)}
Hello everyone, I created a visualization with a lot of REAL, with one or two digits after the decimal point. This causes me problems in terms of rounding and memory... is it possible to display an integer with a comma, like with PROFACE or SIEMENS? It's just an "abuse" of display, the comma is just on the visualization. This limits the memory (16 versus 64 bytes) and rounding is easier to manage... See print screen on proface software THANKS

Post by mikek10 on Error IoDrvEthernetIP: Connection Failure. (16#1) How to solve ^{CODESYS Forge talk (Post)}
Your connection configuration should look something like the attachment. Consuming assembly O->T will be the hex of the assembly you want to reference for output data - I want 102 (DO Data Only) shown in the Wago web page 102 = 16#66. Producing assembly (T->O) is the assembly you require for input data - again shown in the Wago web page - I want 108 (DI Data Only) or 16#6C Then set the number of bytes as per the data in the Wago web page too (both 2 in my case)

Post by comingback4u on Memory Address Overlap ^{CODESYS Forge talk (Post)}
Hello, We use a controller that comes with a bunch of predefined faults. These faults are considered active and historic. They are a 32 byte array but only take up 26 bytes of data. Because of this the historic faults start at address 26 instead of 31. Active faults variable take up address location 0 to 31. Historic faults variable take up address location 26 to 57. Because of this overlap I get an error that these overlap and it wont allow me to download to my controller. This isn't an issue in 3.5.5.4 but becomes an issue in newer version. Is there a way to turn this off? If I change the address location, the historic faults then become broken without doing some manipulation in the code. The software will build just fine. Thank you for your time.

Post by gilbertamine on Comparing Arrays of structure ^{CODESYS Forge talk (Post)}
Hi Everybody, I'm looking for a simple way of comparing two array of a structure. My structure is define like this : TYPE Positions_T : STRUCT PosX: DINT; PosY: DINT; PosZ: DINT; END_STRUCT END_TYPE I have multiples Var : ARRAY [0..220] OF Positions_T, that I need to compare quickly. I don't really want to do a Loop that goes by every 220 points and compare each one of them so I was wondering if there is another way. I came accross the MEM.Compare function, but it require to know the size in Bytes of the memory, and I don't know how to do that... Has anybody an idea on how to do the comparing easily ? Thanks in advance

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)
