Description of BS 6556-3:1985 1985

This Part of BS 6556 specifies two message protocols employed with particular low speed digital signals systems for use in coal mines, using either optical coupling (see BS 6556-1) or transformer coupling (see BS 6556-2). Either protocol can be employed in either transmission system.

The protocols require only limited station intelligence for successful implementation. One protocol, known as simple asynchronous protocol, is designed to work in point-to-point or multi-drop configurations. The other protocol, known as data only protocol, will only work in point-to-point configurations.

Protocol for the applications data is not specified by this standard although industry standards will exist to regulate this.

NOTE The titles of the publications referred to in this standard are listed on the inside back cover.



Specifies the message protocols employed with intrinsicaly safe transmitting and receiving circuits forming low speed digital data transmission links in which the data is transmitted by optical or transformer couplings.
