This section explains the syntax of main and service programs in OpenTP1 UAPs. Main and service programs must be created for an SPP or MHP; only a main program must be created for an SUP.

• Create a main program (SUP, SPP, MHP)
• Create a service program (SPP)
• Create a service program (MHP)

TP1/LiNK can use only SUPs and SPPs as OpenTP1 UAPs. MHPs, CGWs, and SGWs are not available for TP1/LiNK.
