Resetting the Option Module on
Setting a Master-Slave
Hierarchy (Optional)
This procedure is only required if Datalinks are used to write or read
data of the drive or its connected peripherals. A hierarchy determines
the type of device with which the Option Module exchanges data. In a
Master-Slave hierarchy, the Option Module exchanges data with a
master, such as a scanner (1756-DNB, 1771-SDN, 1747-SDN, etc.).
Enabling Datalinks To Write Data
The controller output image (controller outputs-to-drive) can have
anywhere from 0 to 16 additional 32-bit parameters (Datalinks). The
number of additional parameters is configured using Device Parameter
02 - [DLs From Net Cfg].
Important: Always use the Datalink parameters in consecutive
numerical order, starting with the first parameter. For
example, use Host Parameters 01, 02, and 03 to configure 3
Datalinks to write data. Otherwise, the network I/O
connection will be larger than necessary, which needlessly
increases controller response time and memory usage.
Host Parameters 01 - [DL From Net 01] through 16 - [DL From Net
16] control which parameters in the drive, Option Module, or any other
connected peripheral receive the values from the network. The
enhanced PowerFlex 7-Class HIM, DriveExplorer, and DriveExecutive
provide user-friendly screens to help select the drive or peripheral by
port number and the parameter by name. As an alternate method, the
parameter value can be set manually by number using this formula:
From Net Parameter Value = (10000 * port number) + (Destination Parameter Number).
For example, suppose you want to use Host Parameter 01 - [DL From
Net 01] to write to Parameter 03 of an optional encoder module plugged
into drive Port 5. Using the formula, the value for Host Parameter 01 -
[DL From Net 01] would be (10000 * 5) + (3) = 50003.
1. Set the value of Device Parameter 02 - [DLs From Net Cfg] to the
number of contiguous controller-to-drive Datalinks that are to be
included in the network I/O connection.
