Part E Operation and Maintenance
This part describes how to carry out check tasks during daily operations of the field wireless sys-
tem, carry out maintenance when a warning or error occurs, and add and replace components of
the field wireless system.
E1. Routine Maintenance
For the field wireless network, it is important to monitor the degree of stability communications
after the setup task was completed and the system started normal operations. A wireless com-
munication may become unstable due to the influence of obstacles on radio waves on the com-
munication path. Particular care is required to extend a new building or equipment, temporarily
install a metallic structure for construction or maintenance work, or use construction equipments.
E1.1 Routine Maintenance
E1.1.1 Operation Status of Wireless System
For routine maintenance, start the Monitor on the Field Wireless Management Console through a
PC connected to the YFGW410 in order to monitor the status of the wireless system.
When placing a PC for starting the Monitor near the YFGW410 to take tasks, connect it to the
maintenance interface of the YFGW410. When working in secured room or other place in which
host applications are running, connect the PC registered in the access control list to the field
network interface.
For routine maintenance, check by the Monitor that the status information of YFGW410,
YFGW510 and field wireless devices are normal.
