Allen-Bradley 1785-LT A

Allen Bradley PROCESSOR MODULE 6K MEMORY PLC-5/12

The Allen-Bradley PLC-5 processors have ports configurable for either a Data Highway Plus messaging communication link or a Universal Remote I/O link. As a Universal Remote I/O port, it can be configured as either an I/O scanner port or an I/O adapter port. As an I/O scanner port, it monitors and controls the I/O on the link by communicating with the I/O adapters for those I/O. As an adapter port, it communicates only with the I/O scanner port on the link, passing a maximum of one I/O rack of input and output data between the two to provide distributed processing.

The scanner-mode PLC-5 controller can:- gather data from node adapter devices in remote I/O racks - process I/O data from 8-, 16-, or 32-point I/O modules- address I/O in 2-, 1-, or 1/2-slot I/O groups- support a complementary I/O configuration - support block-transfer in any I/O chassis - ladder logic program using a language that is representative of relay logic.- performing diagnostics- programming discrete control

From the family of PLC-5 processors, you can choose the processor(s) that you need for your application. Features common to all Classic PLC-5 processors are:
- same physical dimensions use of the left-most slot in the 1771 I/O chassis
- can use any 1771 I/O module in the processor-resident local I/O chassis with up to 32 points per module
- same programming software and programming terminals
- same base set of instructions
- ladder programs and SFCs can be used by any of the PLC-5 processors
