X20SC0806 B&R

Function model "Cyclic stream" was implemented later. From the application's point of view, there is no difference

between function models "Stream" and "Cyclic stream". Internally, however, the cyclic I/O registers are used to

ensure that communication follows deterministic timing.

To install the module according to the UL standard, the following rules must be observed.

Information:

• Use copper conductors only. Minimum temperature rating of the cable to be connected to the

field wiring terminals: 61°C, 28 - 14 AWG.

• All models are intended to be used in a final safety enclosure that must conform with requirements

 for protection against the spread of fire and have adequate rigidity per UL 61010-1 and

UL 61010-2-201.

• The external circuits intended to be connected to the device shall be galv. separated from mains

supply or hazardous live voltage by reinforced or double insulation and meet the requirements

of SELV/PELV circuit.

• If the equipment is used in not specified manner, the protection provided by the equipment

may be impaired.

• Repairs can only be made by B&R.

In addition to the registers described in the register description, the module has additional general data points.

These are not module-specific but contain general information such as serial number and hardware variant.

General data points are described in section "Additional information - General data points" of the X20 system user's

manual.
