Send an Unformatted Process Program. Before sending a multi-block S7F3, the Equipment always first
sends the S7F1/S7F2 Inquire/Grant transaction. The Host may send S7F1/S7F2 before sending S7F3. The
Equipment accepts it, but does not require it.

S7F4 * H<->E
<B [1] ACKC7> . * ACKC7
The Receiver acknowledges the receipt of the Process Program. If the transfer succeeds, ACKC7 will
contain 0x00, and the Receiver stores the new Process Program into its library. Any previous Process
Program with the same PPID is deleted. Any non-zero ACKC7 indicates refusal of the Process Program.
When the Equipment sends S7F4, ACKC7 may contain the following codes. Any non-zero code indicates
that S7F3 has not changed the Equipment Library.
