The minimum distance calculated is the minimum horizontal distance from the outer edge of. the Eurozone Safe-Guarding Mat detection zone to the nearest part of the hazard. The European prEN-999 formula for floor mounted Safe-Guarding Mats is: S = (1600 x T) + 1200mm. S is the minimum safety distance is millimeters. The factor of 1600 is based on the standard assumption of 1600mm/s as the approach. speed. T is the overall stopping time in seconds. The added 1200mm take into account stride length and arm reach.
A client-server network is designed for end-users called clients to access resources (such as files, songs, video collections or some other service) from a central computer called a server.
Modbus/TCP makes the definition of master and slave less obvious because Ethernet allows peer to peer communication. The definition of client and server are better known entities in Ethernet based networking. In this context, the slave becomes the server and the master becomes the client.
