5.2 System Configuration

POINT

When "CONTROL BUS ERR" or "UNIT VERIFY ERR" occurs

It can be considered that noise due to a long bus connection cable causes a malfunction.

Check whether a signal line such as bus cable is placed near the equipment to operate. If the line is close to the equipment, make a distance of 100mm or more from the equipment.

*1 For the extension cables, refer to the MELSEC-Q catalog (L(NA)08032).

*2 When installing the GOT 13.2m or more away from the main base unit, the bus extension connector box is required.

Attach the bus extension connector box to the extension connector of the base unit. Also, connect the connection cable to the bus extension connector box. When using no extension base unit: Attach it to the main base unit. When using the extension base unit: Attach it to the extension base unit on the last stage.

*3 When using Q00JCPU or Q00UJCPU, attach the bus extension connector to the extension base unit. (Connecting it to the main base unit is not allowed)

*4 When using the following functions, use GT15-QBUS(2). GT15-75QBUS(2)L cannot be used.

Used for remote personal computer operation (serial), video display function, multimedia function, operation panel function, external I/O function, RGB display function, report function (when using a PictBridge compatible printer), hard copy function (when using a PictBridge compatible printer), sound output function, functions with the CF card unit or CF card extension unit, Ethernet download, gateway function or MES interface function

However, Ethernet download, gateway function and MES interface function can be used for GT16 by using the Ethernet interface.
