Note The timer will continue to be incremented when the operating mode is
switched to RUN mode.
Example: The interval can be counted between processing A and processing
B without requiring timer instructions. This is achieved by calculat-
ing the difference between the value in A000 for processing A and
the value in A000 for processing B. The interval is counted in 10 ms
units.
CPU Units with unit version 4.0 and later also have a 1-s timer in
A002, which is incremented by 1 every 1 s.
The following new instructions and instruction functions have been added. For
details, refer to the CS/CJ Series Instructions Reference Manual (W340).
These new instructions are supported by the CX-Programmer Ver. 5.0 or
higher only.
• Serial Communications Instructions:
Supporting no-protocol communications with Serial Communications
Units with unit version 1.2 or later:
TXDU(256): TRANSMIT VIA SERIAL COMMUNICATIONS UNIT
RXDU(255): RECEIVE VIA SERIAL COMMUNICATIONS UNIT
Supporting no-protocol communications with Serial Communications
Boards with unit version 1.2 or later:
TXD(236): TRANSMIT
RXD(235): RECEIVE
• Model Conversion Instructions:
When using CX-Programmer Ver. 5.0 or higher to convert a C-series lad-
der program for use in a CS/CJ-series CPU Unit, the C-series
XFER(070), DIST(080), COLL(081), MOVB(082), and BCNT(067)
instructions will be automatically converted to the following instructions.
The operands do not require editing.
XFERC(565) BLOCK TRANSFER
DISTC(566) SINGLE WORD DISTRIBUTE
COLLC(567) DATA COLLECT
MOVBC(568) MOVE BIT
BCNTC(621) BIT COUNTER
The maximum number of SYSMAC BUS remote I/O points per CPU Unit was
800 points (50 words), which were allocated in the SYSMAC BUS Area
(CIO 3000 to CIO 3049).
The maximum number of SYSMAC BUS remote I/O points per CPU Unit has
been increased to 1,280 points (80 words), which are allocated in the SYS-
MAC BUS Area (CIO 3000 to CIO 3079).
The CS Series, including CS1 CPU Units, were designed to have a higher
total number of points, the Units were initially released before the higher spec-
ification had been fully confirmed, so the official specifications were limited to
ensure stable operation.
Almost coinciding with release of CPU Units with unit version 3.0, stable oper-
ation was confirmed at the higher specification, thereby enabling a change in
the official operating specifications.
This expansion in the number of points is not related to any upgrade of the
Units (CPU Units or SYSMAC BUS Remote I/O Communications Units).
