Rockwell Automation MD65 Profibus Communication Card - Manual (Page 33)

Configuring the PROFIBUS Module 4-5
4.5 Setting the I/O Configuration
The I/O configuration determines the number of drives that will be
represented on the network as one node by the module. If the Mode
Jumper is set to the Single mode position, only one drive is
represented by the module and MDI I/O Cfg (parameter 11) has no
effect. If the Mode Jumper J2 is set to the Multi-Drive position, up to
five drives can be represented as one node by the module.
Step 1. Set the value in MDI I/O Cfg (parameter 11):
Drive 0 is the MD65 with the MDCOMM-PBUS module installed.
Drives 0-1 through 0-4 are MD65 and/or MD60 drives that multi-
drop to the RJ45 (RS-485) port on Drive 0. Refer to Chapter 8,
Using Multi-Drive Mode, for more information.
Step 2. If a drive is enabled, configure the parameters in the drive
to accept the Logic Command and Reference from the
module. For example, set Start Source (parameter 36)
and Speed Reference (parameter 38) in a MD65 drive to
“MDI Port 5.”
Step 3. Reset the module. Refer to section 4.6.2, Resetting the
Module.
The module is ready to receive I/O from the master (i.e., scanner).
You must now configure the scanner to recognize and transmit I/O
to the module. Refer to chapter 5, Configuring the PROFIBUS
Scanner, for more information.
