S7,F22 Equipment Process Capabilities Data (PCD) M,H<-E
Description
This equipment message provides the information necessary for the host to create and partially verify the contents of a new
process program or display the object of a process program previously generated by a host or equipment. The PCD defines the
process program content acceptable to the originating equipment.

S7,F23 Formatted Process Program Send (FPS) M,H<->E,reply
Description
This message allows movement of formatted process programs between a piece of equipment and its host system. The values of
MDLN and SOFTREV are obtained from the PCD used to generate the process program. If S7,F23 is multi-block, it must be
preceded by the S7F1/F2 Inquire/Grant transaction.

S7,F24 Formatted Process Program Acknowledge (FPA) S,H<->E
Description
Acknowledges reception of a formatted process program at its destination and whether the process program was accepted by the
interpreter. A returned status of “accepted” by the interpreter means only that the message is understood. The validity of the
contents of the process program is determined through a separate transaction (S7,F27/S7,F28).
