RS1 Data Table Interface
This chapter provides you with the following information:
•
Supported PCCC commands of the RS1 Module.
•
RS1 Module Data Table Structure.
Supported PCCC Command
List
The RS1 Module communicates over RS-232 using the
Allen-Bradley DF1 protocol. The DF1 protocol uses PCCC
(Programmable Controller Communication Commands) to determine
the data format. PCCC describes the action of the message (set or get)
and the location of the data involved. For further PCCC information,
refer to DF1 Protocol and Command Set Reference Manual,
publication 1770-6.5.16.
The RS1 Module responds to the PCCC types shown in the following
table.
Table 5.A
PCCC Types
Data Table Structure
The RS1 Module maintains a data table that allows DF1 devices (such
as an SLC 500 or MicroLogix 1000) to set or request data using
standard PCCC. The data table in the RS1 Module contains:
•
Drive parameter information
•
RS1 parameter information
•
Logic command & status data
•
Speed command & status data
•
Communication status information.
The data table is formatted as integer files and follows the form
shown on the next page.
