2600-13 Press Control Module
MicroLogix 1500 & CompactLogix Resolver Module
Revision 2.1
Chapter 4: Output Registers
(
Eight 16 bits words sent from the PLC to the 2600-13 module)
The data sent from the PLC to the 2600-13 module is divided into nine separate programming blocks. Word
0 always contains the Transmit Bit, a Clear Error bit, a bit that disables all of the physical outputs, and four
bits (bits 0 to 3) that define the function of the programming block.
The Transmit Bit is part of a Programming Sequence used to send data from the PLC to the 2600-13 module.
The following is a description of this programming sequence.
Programming Sequence
1.
The ladder logic program writes the data into the
Output Registers
.
2.
The ladder logic program then toggles the
Transmit Bit
. The 2600-13 module only acts on the data in
the output registers when the Transmit Bit transitions from 0 to 1 or 1 to 0. It will ignore the data in
the output registers when the Transmit Bit is in a constant state.
3.
When the module detects the transition of the
Transmit Bit
, it will examine and execute the command,
and respond by setting any error bits and toggling the
Acknowledge
Bit
in the input registers to be
equal to the
Transmit Bit
.
4.
When the ladder logic program sees that the
Acknowledge
Bit
is equal to the
Transmit Bit
, it will
examine any error bits.
5.
The programming sequence is now complete.
The first of the programming blocks only contains the standard commands that exists in all of the
programming blocks and does not send any additional programming data to the 2600-13 module.
