To optimize network response time, keep the number of global data
registers to a minimum.
EXAMPLE OF SETTING UP PEER COP AND GLOBAL DATA SERVICE
This section describes the steps for configuring the drive controller so that
a PLC at address 3 can control the drive controller via five peer cop
registers and display these states via 14 global data transfers. It is
assumed that the PLC is configured to send five peer cop data items to
the drive controller and receive 14 global data transfers.
1. With the drive controller powered down, set its MODBUS PLUS
address using switches 1 to 6. Leave switches 7 and 8 at zero. For
example, to select address 4, set switches 1 and 2 to 1. The address
can be displayed using operator keypad menu 8, AdrC.
2. Connect the drive controller to the line supply.
