Event Step Transfer Command

Format: 1110 DSSS SSSS SNNN

D Direction. Write (0) or read (1) event step.

S Step number. 0 to 255.

N Field in the event step. 0 to 7.

These commands are used to move event step information to and from the RMC. The D bit shown in the binary expansion of the Event Step Transfer Command register indicates whether the command will write an Event Step value (indicated by a 0) or read an Event Step value (indicated by a 1). Therefore, commands E000 to E7FF set (write) data to the RMC, while commands E800 to EFFF get (read) data from the RMC. The eight S bits specify the step number, and the three N bits represent the field in the Event Step to access. Use the following chart to select the desired field:

To write event step information to the RMC, use the following commands to set the corresponding fields. The command data value will be copied into the corresponding step field:

When using PROFIBUS-DP, you can update multiple words every Programmable Controller scan by using the Command and Data registers for multiple axes. For example, by using one axis to transfer the first half of the table and the second axis to transfer the second half of the table, transfer time can be cut in half.

To read event step information from the RMC, use the following commands to retrieve the corresponding pieces of data from the step table. The data will be available where the Status Area Request is normally returned:
