Modbus Network Address
For multiple PPC installations, each PPC-2010 must have a
unique network address. As many as 32 PPC systems may
communicate on a network. Both port 1 and 2 have the same
network address. Network addresses 1 through 4 can be set
using the rotary switch on the processor module.
Changed communication parameters do not take affect until
the controller resets or cycles power, and only with the
appropriate rotary switch settings on the Processor module.
Use rotary switch setting D and PPCComSu to program the
remaining addresses (5-32). See Setting Programmable
Modbus Addresses on page 87 for programming information.
NOTE! Do not cycle power with the rotary switch set in positions
E-G unless specifically directed to do so. These
positions are used for clearing memory and other
functions. Parameter settings can be lost. See Chapter 4,
Troubleshooting, for more on these switch settings.
