5.4 Data Mapping in Software Configuration Mode
In the “Software Configuration” mode, the data mapping address can be manually configured. The data mapping
relationship between GT200-DP-RS buffer and PROFIBUS DP is shown below. The address N and M (or X and
Y) can be discontinuous number.

For example, in STEP7, add the following modules on the slot. The I address corresponds to input buffer data and
the Q address corresponds to output buffer.
The IB274~281 corresponds to 0000H~0007H of GT200-DP-RS input buffer. The IB300 of next input module
corresponds to 0008H.
The QB272~QB279 can corresponds to 4000H~4007H of GT200-DP-RS output buffer. The QB326~327 of next
output module corresponds to 4009H~400AH.
