70n0:01 Transmit request By changing the state of this bit, the controller informs the module
that the DataOut bytes contain the number of bytes displayed in in-
dex 0x70n0:099 “Output length”.
The module acknowledges receipt of the data by changing the
state of the index 0x60n0:01 “
TransmitAccepted [ } 43] ” bit.
Only now new data can be transferred from the controller to the
module.
BOOLEAN RO 0x00

70n0:02 Receive accepted The controller acknowledges receipt of data by changing the state
of this bit.
Only then new data can be transferred from the terminal to the con-
troller. BOOLEAN RO 0x00

70n0:03 Init request 0:
The controller once again requests the module to prepare for serial
data exchange.
1:
The controller requests the module for initialization.
The transmit and receive functions will be blocked
The FIFO pointer will be reset and the interface will be initialized
with the values of the responsible Settings object. The execution of
the initialization will be acknowledged by the module with the “
Init
accepted [ } 43] ” bit in index 0x60n0:03.
BOOLEAN RO 0x00

70n0:04 Send continuous Continuous sending of data from the FIFO.
The send buffer is filled (up to 128 bytes) by the controller. The
filled buffer contents will be sent on the rising edge of the bit.
If the data has been transmitted, the module informs the controller
by setting the “
Init accepted [
}
43] ” bit in index 0x60n0:03. “Init ac-
cepted” is cleared with “Send continuous”.

In operation mode
“RS232, manual operation” (CoE

of Tx output can be set manually here.
Sending and receiving data is not handled by the firmware in this
operation mode.
