Introduction

When using a 1772-SD2 remote I/O scanner/distribution panel, the I/O
device capacity can be increased from 896 to 1,792 I/O. The increase is
accomplished through configuration of the racks and programming. For
more information, refer to the Remote I/O Scanner/Distribution Panel
Product Data (publication 1772-2.18).

With the proper interface module, the PLC-2/30 processor can be
connected to the Allen-Bradley Data Highway or other industry standard
buses. Table 1.B lists several “from-to” possibilities and the Allen-Bradley
module used to accomplish that function.

Non AllenĆBradley implies using Data Highway or Data Highway II to communicate with industry standard devices. See the

individual product brochures for specific connectivity information.

Industrial Terminals (cat. no. 1770-T1 or -T2) can be used on a limited
basis to program a PLC-2/30 programmable controller. Be aware that
only features supported by these terminals may be entered. The 1770-T3
and 1784-T50 terminals provide full PLC-2/30 capability. Refer to the
Industrial Terminal System User’s Manual (publication 1770-6.5.3 or
1784-6.5.1) for details.
