HB97E - CP - RE_240-1CA20 - Rev. 12/42 3-15
This FC serves for data transfer from the CPU to a partner station. The
target at the partner station is transferred together with the user data Here
the source area of the own station is defined by QDB, QBDW and LANG.
The target area in the remote station is defined by ZDB and ZBDW.
With calling the FC it is checked by means of the check bits if there is an
order just running. If the control bits are reset a new SEND order is
released.
Here a frame header with user data is transmitted to the CP after that the
system waits for the response message.
The indicator word indicates "Order just running" as long as the response
message was not received. Only after the receipt of the response message
the flag "Order ready" of the indicator word is set and the communication to
the CP is finished.
This function is cyclically called as long as "Order ready with/without error"
is set at the indicator word.
With an error during communication the CPU gets an error number from the
CP. Then the error number is transferred to the indicator word and the bit
"Order ready with error" is set. Then the communication to the CP is
finished.
