= Transfer time for process image update
The tables below show the various portions of the transfer time for a process image update
(process image transfer time). The specified times only represent "ideal values", and may be
extended accordingly by any interrupts or communication of the CPU.

In the case of I/O inserted into the central controller or expansion device,
the specified value includes the execution time for the I/O module
The module data is updated with the minimum number of accesses.
(example: 8 bytes result in 2 double word accesses; 16 bytes in 4 double word accesses.)
