Range of
values:
0 to 255 ms
Default:
0
Name:
Send delay time
Explanation:
The send delay time is only used if the clear to send (CTS) signal has been
recei
ved from the modem (if it exists) and no time was set for the RTS/CTS
delay time.
As soon as the CTS signal is received from the modem, the send delay time
is started. The transfer of the data starts only after the time has elapsed.
Range of
values:
0 to
65535 ms
Default:
0
0 = no send delay time
Name:
Data format
Explanation:
Format with which individual characters are transferred
Range of
values:
•
8 data bits, odd parity, 1 stop bit
•
8 data bits, even parity, 1 stop bit
•
8 data bits, no parity, 2 stop bits

The "ModbusWrite" object
The "ModbusWrite" object
To map the data to be written between the S7 CPU and MODBUS slaves, the
"ModbusWrite" object is available. A separate "ModbusWrite" object is configured for each
MODBUS slave.
The input address
Data written from TD7onTIM to the MODBUS slaves is read from the input address area of
the CPU. Only the specified address areas can be read by TD7onTIM. Data from other
areas, for example analog values acquired over peripheral input words (PIW) must be
mapped to the bit memory or data block area by the user program.
Name:
S7 CPU input address
Memory area:
The following options are available for the source address:
•
DB: Data block
•
Memory bit: Memory bit area
•
Input: Process input image (PII)
