RMC70/150 and RMCTools User Manual

In step 43, the Element is 10 (A in hexadecimal).
In step 44, the File is set to 56 (38 in hexadecimal).
In step 45, the count is set to3.
In steps 46 to 48, the write values are entered.
In step 49, bit 31 is set to 1 for a write.
In step 50, bit 30 is toggled to request the write.




6.9.5.5. PROFIBUS Mode: Enhanced+

The Enhanced+ mode is one of the Basic/Enhanced PROFIBUS Modes available only on the

RMC75P. Most users will prefer the I/O Modes instead.

Features

This mode has the following features:

Sixteen (16) user-selectable cyclic read registers are continuously read for instant

access by the PLC or PC.

See the Response Block and Setting Up the Indirect Data Map sections below.

One (1) register anywhere in the RMC70 can be explicitly written or read.

See Read Any Single RMC70 Register and Write to Any Single RMC70 Register

below.

Seven (7) contiguous registers in the RMC70 can be explicitly written or read.

See Read Any Contiguous RMC70 Register and Write to Any Contiguous RMC70

Register below.

Commands can be issued to any number of axes simultaneously.

See Command Block, Issue a Single Command, and Issue Simultaneous

Commands below.

PROFIBUS bandwidth used: 2 blocks of 16 consistent I/O words (16 bits each), plus 16

consistent Input words (16 bits each).

RMC70 Register Addresses for PROFIBUS

When communicating over PROFIBUS, the RMC70 registers addresses use the same

file:element addresses as the RMC70 IEC-61131 addresses.
For example, to read the Axis 0 Actual Position via PROFIBUS, notice that its address is

%MD8.8. Therefore, the address via PROFIBUS is file 8, element 8.

Parameterization

Enhanced+ mode requires the PROFIBUS configuration and parameterization listed below.

The GSD file does direct the PROFIBUS master setup software to automatically set up

these values, but Delta has found several cases where it is not supported correctly or

manual setup is otherwise required.

Configuration: FF DF FF
