PLC-5 ASCII I/O Module
Description

Informationen zu diesem Produkt

Hier ist alles, was Sie wissen müssen


The Allen Bradley 1771-DA is an ASCII I/O module that fits into a 1771 I/O chassis. With the ASCII module you can transfer data, by means of the I/O scan, from an ASCII device to the PC processor table and vice versa. The module has two modes of operation, data mode and report generation mode. In data mode, you can transfer ASCII, BCD or hex characters. Generally, use this module to transfer data to the processor data table. In report generation mode, you can include BCD values in the string of ASCII characters. Gernerally, use this mode when you want to transfer messages.

You can use your ASCII module with any Allen Bradley programmable controller that has an expandable data table, block transfer capability and uses the 1771 I/O structure. If you use a PLC-2/20 controller (cat. no. 1772-LP2), your programming will be lengthier because its processor does not have file move or block transfer instructions.
