Part E Operation and Maintenance

This part describes how to carry out check tasks during daily operations of the eld wireless sys-

tem, carry out maintenance when a warning or error occurs, and add and replace components of

the eld wireless system.

E1. Routine Maintenance

For the eld 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 inuence 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.

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 eld

network interface.
