BLOCK MOVE VALUE IN %MW#.... TO %MW#... IN SOMACHINE v4.3
KY WONG posted a topic in Modicon / Telemecanique / Schneider Electric
Hi, I am learning on Schneider PLC Programming. May I know is the Schneider PLC Programming have a same function of "Block move" in Mitsubishi PLC which can move a few number of address value to another address in once time. What is the code of it?Example, I wish to move %MW1 (Int) until %MW10 (Int) to %MW100 (Int) until %MW110 (Int). Is there any code can done it in once? I am using Schneider PLC TM241 model with Somachine V4.3 Programming Software. @Wasan, Hi, Do you familiar with Schneider PLC Programming? -
Hi friends, I am using G(P).CPRTCL to create the RS485 communication code to control my OMRON Temperature controller Modbus. However, I find out that the generate crc-16 code for my comment is different from the calculated MODBUS CRC-16 . How can it be? I am using predefine function of PLC. It should give me a correct crc-16 right? @Wasan, @kaare_t

@Wasan Thank for your help and solution. Thank you very much.

Because there is no any error is given by the plc . I think my system is waiting for the answer from external device. Is there any place can adjust the waiting message ?

Hi friends, I am facing a problem. When my device is suddenly disconnect with RS485 modbus connection, my QJ71C24N card is not no error coming out and it refuse to continuous sending out signal even my program is keep calling on for G(P).CPRTCL . How can I reset the situation without turn off my PLC and how can I detect it which is not given me any error condition? @Wasan @kaare_t

@Wasan, @kaare_t Please help.

I got a problem when i using the predefined protocol support function of GX work2. When i write the setting into the module, there is a message come out. Any of you facing this problem before? and how can I solve it? Need help.

Problem solve. Thank you very much. @kaare_t & @Wasan

@kaare_t & @Wasan thanks for helping me to solve the problem. I am grad to meet you here. Thank you very much.

Any one have any experience to due with Parity Error when RS485 input can't get? Below is the circuit trace i get. It shown me that Parity Error when input signal from my device. But some of the time I can get the input message completely. Sometime can't. Is there any way to solve it?

@Wasan I have just get 1 more issue. What is this mean? Do you have this experience before?
-
@Wasan Here is the setting of my plc and the code of PLC program.

@Wasan I have adjust the setting of echo back function. However, I still get the echo back in my input. Is there any setting I need to adjust?
-
@Wasan My device end code is <CR> only. It mean that my receive complete code specification setting is 13(Dh) right? The entire received input will go to specify buffer memory right?

@kaare_t I wish to understand about the checksum. For your information, my ASCII Modbus device is using CheckSum8 Xor. Is there any PLC code can generate the Checksum for it? For your information, now I temporary off the function of checksum in my device function. Before this, I have used the FX PLC RS485 communication (RTU modbus format). As I know there is a PLC code to generate the CRC-16/Modbus. Is the Q series having the special code to generate the CRC too?
