Conversion Type
The BCC calculation result is converted or not according to the designated conversion type as described below:
Example:
BCC calculation result is 0041h.
(1) Binary to ASCII conversion
(2) No conversion
BCC Digits (Bytes)
The quantity of digits (bytes) of the BCC code can be selected from 1 or 2.
Example:
Transmit Completion Output
Designate an output, Q0 through Q21, or an internal relay, M0 through M1277, as a device for the transmit completion output.
Special internal relays cannot be used.
When the start input for a TXD instruction is turned on, preparation for transmission is initiated, followed by data transmission.
When a sequence of all transmission operation is complete, the designated output or internal relay is turned on.
Transmit Status
Designate a data register, D0-D1998, as a device to store the transmit status information including a transmission status code and
a user communication error code.
Transmit Status Code
If the transmit status code is other than shown above, an error of transmit instruction is suspected. See User Communication Error
Code on page 26-32.
Note:
On WindLDR, Modbus ASCII is defaulted to
binary to ASCII conversion.
Note:
On WindLDR, Modbus RTU is defaulted to no
conversion.
Note:
On WindLDR, Modbus ASCII and Modbus RTU
are defaulted to 2 digits.

Preparing transmission
From turning on the start input for a TXD instruction, until the transmit data is
stored in the internal transmit buffer

Transmitting data
From enabling data transmission by an END processing, until all data transmission
is completed
48
Data transmission complete
From completing all data transmission, until the END processing is completed for
the TXD instruction
64
Transmit instruction complete
All transmission operation is completed and the next transmission is made possible
