When pin 8 is set to RUN (ON), the CPU will start in RUN mode upon power
application. When set to STOP (OFF), the CPU will start operation in PRO-
GRAM mode. (Refer to to the 2-2-4 PC Operation Mode for further details.)
When pin 8 is set to MONITOR (ON), the PC will operate in MONITOR mode
upon the application of power. When the pin is set to NORMAL (OFF), the PC is
no longer controlled by the Host Link Unit (i.e., the mode of operation will be de-
termined by other system conditions). Refer to the 2-2-4 PC Operating Mode for
details.
Set pin 5 of SW2 to OFF (operating level 1) when using a C500 PC and ON (op-
erating level 0) when using the Host Link Unit together with a SYSMAC NET Link
Unit. When using two Rack-mounting Host Link Units, set this pin to ON for one
of the Units, and to OFF for the other.
Failure to set pin 5 correctly may damage components or prevent operation.
ON (Single-link)
If pin 6 is set to ON, the Host Link Unit is connected to the host computer on a
one-to-one basis (see Example 3 under 1-2 System Configuration). The Unit
number and Frame Checksum (FCS) settings are not required. The normal set-
ting is OFF (see below).
OFF (Multiple-link)
If pin 6 is set to OFF, up to 32 Host Link Units can be connected to one host com-
puter. The unit number and FCS must be specified, even if only one Host Link
Unit is connected to the host computer. When using Ladder Support Software,
LSS, pin 6 must be set to OFF.
1. Enables data areas to be read and, when the CPU has been correctly set via
2: Enables program transfers and reading or writing of I/O tables.
3: I/O reads can be performed and I/O tables can be registered. The Com-
mand Level should be set to 1, 2, and 3 for running LSS software, program trans-
fers, etc. Other levels may be used for Systems Control Software, monitoring,
Data Acquisition Software, etc.
The Mode Selector (3G2A5-LK101/201) sets the Host Link Unit in to HOST or
LOCAL mode. In HOST mode, the host computer can set the operating mode of
the PC or write data to its memory. In LOCAL mode, the operating mode is speci-
fied by a programming device connected to the PC; such as a Programming
Console. This switch is locked by removing the key with the HOST mode se-
lected. See 2-2-4 PC Operating Mode for further details.
By pressing the Reset Switch the Host Link Unit is forced to the initial status.
Sets the Host Link Unit to either an internal or external clock. Normally, an inter-
nal clock is employed. But, when a synchronization modem with a baud rate of
2,400 bps or higher is used, the external clock setting must be selected.
the SC (Status Write) command, data can also be written.
