C500 (3G2A5) Host Link Units
* A CPU-mounting Host Link Unit must be set to STOP mode when used together with a Rack-mounting Host Link Unit
** If a Programming Console is also mounted, the mode selector on the Programming Console determines the PC
PC Mode When Mounting a CPU-mounting Host Link Unit with the Power ON
* If there is no Rack-mounting Host Link Unit mounted, data for the Rack-mounting Host Link Unit LOCAL mode applies.
** V1 PCs are the C200H/HS/HX/HG/HE, C1000H, C2000H, and any other building-block PC with the suffix “V1” in the
model number.

System configuration
If a peripheral device other than a CPU-mounting Host Link Unit is attached to
the CPU, the PC’s operating mode is determined by the peripheral device when
the Host Link Unit’s mode selector is set for LOCAL. With the mode selector set
for HOST, the PC’s operating mode is determined by the RUN/STOP selector on
the Host Link Unit.
Unless programming is implemented to prevent starting, if the PC is in RUN
mode, it will begin operation immediately the power is applied. Refer to
Controlling PC Start-up at the end of this subsection for details on programming
methods. These methods do not apply when using a 3G2A5-LK101-(P)EV1 or
3G2A5-LK201-EV1 Host Link Unit.
The following figures show the flow of data between the system and a Program-
ming Console with the Host Link Unit set in HOST mode. As can be seen, the
Programming Console can be used for monitoring or writing in this mode.
