IM 01W02D01-01EN
In the redundant YFGW410, need to connect the system to the YFGW510 using following meth-
od:
• Direct connection between YFGW410 and YFGW510 (shown in Figure A3-1)
• A single L2SW is installed for each backbone device. The L2SW have to connect as a loop.
(shown in Figure A4-1).
For the recommended L2SWs whose operations have been proven on the field wireless back-
bone system, see Section G2.7 Recommended Device List. If a non-recommended L2SW is
used, its operation is not guaranteed even when the above functional requirements are satisfied.
IMPORTANT
When connecting the L2SW between YFGW410 and YFGW510, requirements for operation to
the backbone network are the following.
- Use IEEE1588 v2 compliant product to L2SW.
- Enable Rapid Spanning Tree Protocol (RSTP) or another loop detection function.
IMPORTANT
When CENTUM VP is running, set and adjust the parameters of the field wireless device from
PRM.
When CENTUM VP is not running, or when a non-Yokogawa host system is connected, the pa-
rameters can be set and adjusted using FieldMate.
IMPORTANT
When CENTUM VP is used with YFGW410 in redundant configuration, CENTUM VP R5.02.00
or higher is required. For details, see the Communication with Subsystems Using FIO user’s
manual (IM 33K03L20-50E).
