4.3.1 I/O Update Enable Logic Summary
The logic strings shown in figure 4.1 summarize the output and input enable logic
described in this chapter.
4.4 Setting Up Data Types That Can Be Transferred
You must enable the transfer of tunable and configurable inputs from the Network
Option board to the Regulator board. Until you enable transfer, only control/reference
data are read by the Regulator board.
To enable transfer of tunable and configurable data, set the network-master-controlled
Tune/Config Input Enable bit (Drop_1, register 32, bit 14) to 1.
For example, the master application program would typically:
1. Initialize the tunable and configurable input data in the dual-port memory of the
master’s Network module
2. Delay for an appropriate amount of time to ensure data have been transferred to
the drive
3. Set the Tune/Config Input Enable bit to 1.
If you only want to transfer control/reference data, leave the Tune/Config Input Enable
bit at 0 (off). This forces you to configure the drive through another source, such as the
OIM , CS3000 software, or WebPakCS software, but allows you to control the drive
(including RUN , JOG , STOP , RESET , and the reference) from the network master.
