Set pin 5 of SW2 to OFF (operating level 1) when using a C500(F) PC and ON
(operating 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.
upon the application of power. When the pin is set to NORMAL, the PC is no
longer controlled by the Host Link Unit (i.e., the mode of operation will be deter-
mined by other system conditions). Refer to 2-3-4 PC Operating Mode for de-
tails.
ON (Single-link)
the host computer on a one-to-one basis (see Example 3 and Example 5 under
1-2 System Configuration. The Unit number and Frame Checksum (FCS) set-
tings are not required. The normal setting is OFF (see below).
OFF (Multiple-link)
connected to one host computer. 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.
Pins 7 and 8 on SW2 control the operating command levels according to the fol-
lowing:
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.
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.
