7.Communication Profile Family SNpFAMILY(SafetyNET p1)- RTEcommunication profiles
7.1General overview
Communication Profile Family SNpFAMILY defines profiles based on IEC/PAS 61158-3-22through lECIPAS 61158-6-22.
In this part of IEC 61784,the following communication profiles are specified for CPFSNpFAMILY.
.Profile SNpFAMILY/1
This profile defines protocol and service selection for devices which utilize thecommunication model real time frame line (RTFL).
Profile SNpFAMILY/2
This profile defines protocol and service selection for devices which utilize thecommunication model real time frame network(RTFN).
7.2Profile SNpFAMILY/1
7.2.1 Physical layer
The physical layer shall be based on standard Ethernet hardware according toISolIEc8802-3.
CP SNpFAMILY/1 devices shall use a data rate of 100 Mbit/s and full-duplex transmissionmode. A combination of full-duplex and 100Base-TX with auto crossover function (wire，2twisted pairs) should be used.
When using cables, they shall be rated Cat5e or better, and shielded in an appropriate way(FTP,STPor SFTP) depending upon EMC constraints.
7.2.2Data link layer
Data link layer is described in IEC/PAS 61158-3-22 and IEC/PAS 61158-4-22. Table 1specifies the use of the services included in this profile. Table 2 specifies the use of theprotocol included in this profile.
