7 Communication Profile Family SNpFAMILY (SafetyNET p 1 ) – RTE
communication profiles
7.1 General overview
Communication Profile Family SNpFAMILY defines profiles based on IEC/PAS 61 1 58-3-22 through IEC/PAS 61 1 58-6-22.
In this part of IEC 61 784, the following communication profiles are specified for CPF SNpFAMILY.
• Profile SNpFAMILY/1
This profile defines protocol and service selection for devices which utilize the communication model real time frame line (RTFL).
• Profile SNpFAMILY/2
This profile defines protocol and service selection for devices which utilize the communication model real time frame network (RTFN).
7.2 Profile SNpFAMILY/1
7.2.1 Physical layer
The physical layer shall be based on standard Ethernet hardware according to ISO/IEC 8802-3.
CP SNpFAMILY/1 devices shall use a data rate of 1 00 Mbit/s and full-duplex transmission mode. A combination of full-duplex and 1 00Base-TX with auto crossover function (wire, 2 twisted pairs) should be used.
When using cables, they shall be rated Cat5e or better, and shielded in an appropriate way (FTP, STP or SFTP) depending upon EMC constraints.
7.2.2 Data link layer
Data link layer is described in IEC/PAS 61 1 58-3-22 and IEC/PAS 61 1 58-4-22. Table 1 specifies the use of the services included in this profile. Table 2 specifies the use of the protocol included in this profile.
