Power supply (24V DC) for EP010 comes from the FBP. Connected Modbus device,

however, must be indipendently powered.

2.3.1 Earthing

Terminal PE has to be connected to earth.

An address must be set on every field bus plug. The possibilities for setting the address very

depending on the type of the field bus.

Once the address is set, it is stored in the field bus plug, even in case of supply voltage

breakdown.

Addressing of the EP010 is performed by the connected field bus plug.

In the field bus plug,address is stored voltage breakdownss is stored voltage breakdown-safe.

The following methods can be used for addressing:

The address is set on the field bus plug by means of the programming unit. For this purpose,

the cable of the field bus plug is disconnected from the bus and than connected to the handheld

programming unit.

The ABB FBP Addressing Interface (CAS21-FBP.0, Order n. 1SAJ929003R0001) is the

requested handheld programming unit.

In this case, the address is transmitted from the controller to the field bus plug via the field bus

(refer to corresponding FBP FieldBusPlug description, see [1]).

A defective EP010 can be replaced without any problems. After disconnecting Modbus cables

and the FieldBusPlug, the EP010 can be dismounted and replaced.

ABB SACE

EP010 doesnt't store the address given by the field bus plug.

Remember that the address associated to the device via EP010 is stored into

FBP. Therefore, after installation, the new EP010 takes on the same address as

the replaced one.
