4.1 Consideration when planning the system
Issues for the Network Conception
 The ILX69-PBS has address rotary switches to set an station address from 0 to 99. If set
to 0, address will be taken from the configuration assembly. Using the PLCs
configuration data, an address range from 0 to 125 is adjustable.
 The ILX69-PBS is capable of automatic baud rate detection.
 A 1769-ECR (right end cap) or 1769-ECL (left end cap) is required to terminate the end
of the Compact I/O bus.
 Each bank of Compact I/O must have its own power supply.
 A Compact I/O power supply has limits on the amount of +5 VDC and +24 VDC current it
can supply to modules in its I/O bank. These limits depend on the catalog number (e.g.
1769-PA2) of the supply. A bank of modules must not exceed the current limits of the I/O
bank power supply. Refer to the Compact 1769 Expansion I/O Power Supplies
Installation Instructions.
 The ILX69-PBS has a distance rating of 2. Therefore, the module must be within 2 slots
of the I/O bank’s power supply.
Configuration and Network Communication
 Determine the PROFIBUS baud rate based on standard PROFIBUS system
considerations.
 Identify the number of words of I/O data each slave supports.
