Using This Manual
This concepts manual helps you apply the SPI module to your application.
It serves as a supplement to the SPI user manual (publication 1771-6.5.97).
The purposes of this concepts manual are to help you:
understand SPI terminology and concepts of SPI module operation
understand relationships among the various “custom” data blocks for
– module-specific configuration
– device-specific configuration
– the transfer of data to and from the device via the SPI module
apply the custom-configured scheme of SPI communication
program the correct protocol for block transfers to / from the SPI module
map the data table for the various command and status blocks
wire the primary and secondary machine connections to the SPI network
troubleshoot with diagnostics that indicate the source of the fault
To help achieve these objectives, we provide example diagrams and
worksheets.
This manual assumes that you are a first-time user of the SPI module,
but that you are experienced with the following:
programming a PLC-5 processor with 6200 Series Software
programming the block transfer of multiple data blocks
creating operational interface software for a PLC-5 processor
using the hexadecimal numbering system
To set up a minimal SPI network, you should have at least the following:
1771-SPI module
1771 I/O chassis and power supply
PLC-5
processor
SPI-specified device
personal computer or programming terminal
6200 Series Software for programming a PLC-5 processor
