4-12 Configuration and Programming

PGMn: Program Counter Number Bits

(Word 0, Bits 08 to 11)

These four bits select the counters to which the programming block is

applied. If the bit is reset, the associated counter is not programmed

and the counter can be running when this block is sent. In addition,

the associated programming words must be zero or a programming

error occurs. A counter must be stopped when programmed with this

block.

CType: Counter Type Bit

(Words 1 and 3, Bit 00; Word 5, Bits 00 and 08)

For each counter, this bit defines whether the counter is a ring or

linear counter.

Input Config: Input Configuration Bits

(Words 1 and 3, Bits 01 to 03)

These bits define the input configuration for Counters 1 and 2.

Counters 3 and 4 are always Pulse/Internal Direction counters and do

not require programming bits. The table below shows the input

configuration programming bit values.
