1-4-7 SYSMAC NET Link and SYSMAC LINK Capabilities
The SYSMAC NET Link and SYSMAC LINK Systems are high-speed FA net-
works which can be used with the C200HS-CPU31-E and C200HS-CPU33-E
CPUs and the following Units:
SYSMAC NET Link Unit: C200HS-SNT32
SYSMAC LINK Units: C200HW-SLK13/SLK14 (optical fiber cable)
C200HW-SLK23/SLK24 (coaxial cable)
Data can be exchanged with the PCs in a SYSMAC NET Link or SYSMAC LINK
System using the SEND and RECV instructions.
1-4-8 Built-in RS-232C Connector
Host link communications are possible using the RS-232C connector built into
the C200HS-CPU21-E/CPU21-EC/CPU23-E/CPU31-E/CPU33-E CPU. By
using the TXD and RXD instructions, RS-232C communications is possible
without using time-consuming procedures. A 1-to-1 link using the LR Area or an
NT link with the Programmable Terminal (PT) allows high-speed communica-
tions.
1-4-9 More Flexible PC Settings
With its default settings, the C200HS can be used like a C200H PC, but the
C200HS’s new settings provide more flexibility and allow it to be adjusted to fit
particular applications. These new settings are described below.
DIP Switch Settings The 6 pins on the C200HS’s DIP switch are used to write-protect part of UM, set
the CPU to automatically transfer Memory Card data to UM, and other functions.
UM Area Allocation Portions of the UM area can be allocated for use as the Expansion DM Area and
I/O Comment Area. (Most of the UM area is used to store the ladder program.)
PC Setup DM 6600 to DM 6655 is set aside for PC Setup data. The PC Setup determines
many operating parameters, including the startup mode and initial Special I/O
Unit area.
1-4-10 Debugging and Maintenance
New functions such as data trace and differential monitor have been added,
making it easier to check status changes. These and other new functions are
covered in detail in the C200HS Operation Manual (W235).
1-4-11 Peripheral Devices
With the C200H, Peripheral Devices had to be connected through a Peripheral
Interface Unit or Host Link Unit, but with the C200HS Peripheral Devices can be
connected to the PC through a CQM1-CIF02 Connecting Cable.
I/O Comments Stored in PC By allocating a part of UM as the I/O Comment area, it is no longer necessary to
read I/O Comments from a Peripheral Device’s floppy disk. If the Peripheral De-
vice is connected to the C200HS online, the ladder diagram can be viewed with
I/O comments.
Online Editing A “CYCLE TIME OVER” error will no longer be generated when the program in
the PC itself is being edited online.
