How to Switch Programs in DataMan Via a Single DMCC Command Using Profinet

How to use Profinet commands to send a single DMCCs when using Siemens PLCs.

ATTENTION: This procedure is valid only for reader model DataMan 290, DataMan 390.

Answer

You will need to use the following command to switch the Program, receiving this command will enable the specified Program.

For example, please follow the steps as below to enable Program 0.

||>SET PROGRAM.ENABLE 0 Put ||>SET PROGRAM.ENABLE 0$R$L in “User Data”.

DMCC command string must first be placed in “User Data” before invoking this event, and we need put $R$L instead of \r\n when using Siemens software.

Set “Execute DMCC” bit to “True” to invoke the DMCC operation, and

then “Execute DMCC Ack” also will be set to “True” once the “Execute DMCC” operation is complete.

Reset “Execute DMCC” bit, and then “Execute DMCC Ack” will be set to “False” as well.
