Configuring the Module
3-9
A hierarchy determines the type of device with which the module
exchanges data. In a Master-Slave hierarchy, a module exchanges data
with a master, such as a scanner or bridge. In a Peer-to-Peer hierarchy, a
module exchanges data with one or more EtherNet/IP modules connected
to devices that have compatible Logic Command/Status words.
For both master-slave and peer-to-peer hierarchies, the devices
exchanging data must be on the same IP subnet. See “IP Addresses” in
the
for information about IP subnets.
To set a Master-Slave hierarchy
1. Enable the desired I/O in Parameter 32 - [SP I/O Cfg]. Refer to
in this chapter.
2. Set the bits in Parameter 45 - [M-S Input]. This parameter
determines the data received from the master by the drive. A “1”
enables the I/O. A “0” disables the I/O.
Bit 0 is the right-most bit.
3. Set the bits in Parameter 46 - [M-S Output]. This parameter
determines the data transmitted from the drive to the scanner. A “1”
enables the I/O. A “0” disables the I/O.
Bit 0 is the right-most bit.
