Delta RMC151 - Manual (Page 545)

6 Communication
• Axis 0 Actual Position
• Axis 1 Status Bits
• Axis 1 Actual Position
• Task 0 Current Step
• Task 1 Current Step
• The first 8 registers of the Variable Table.
In addition, the user would like to read some other registers occasionally.
Implementation
• First, PROFIBUS communications requires that Axis 0 Status Bits register
must be in the first Response Block register, which is entry 0 in the Indirect
Data Map.
• Second, the Read Response register is needed in order to read other
registers occasionally.
• Third, the user determines which registers must be in registers 0-7 to
preserve consistency. The rest of the registers can then be placed in the
remaining registers.
The user chose to set up the Indirect Data Map like this:
Using the Data Blocks
Issue a Single Command
To issue a command, set up the contents of the first six registers of the Command Block,
and when complete, toggle the Command Request bit in the first Command Block
register.
Notice that commands with more than 5 command parameters cannot be issued via
PROFIBUS. To issue such commands, include them in a user program and issue a
command via PROFIBUS to start the user program.
