<br />
Syntax for setting the slaves:<br />
<br />
01_parameter phrase for the first Modbus TCP slave<br />
<br />
02_parameter phrase for the second Modbus TCP slave<br />
<br />
...<br />
<br />
10_parameter phrase for the tenth and last Modbus TCP slave<br />
<br />
The parameter phrases of the slaves must be numbered consecutively, otherwise reading the parameters is stopped at the gap.<br />
<br />
Example:<br />
<br />
01_IPAdr=192.168.0.80<br />
02_IPAdr=192.168.0.81<br />
06_IPAdr=192.168.0.84<br />
<br />
The sequence is stopped at 03_. In this case, only the settings for the slaves from 01_ to 02_ are read.<br />
<br />
<br />
'''PLC43.INI parameterisation'''<br />
<br />
The parameterisation fo the PLC43.INI can be conducted manually or with the help of the user inteface.<br />

<br />
The number of parameters, that are to be generated for one slave, depends on the used Modbus function (see chart).<br />
<br />
To be able to query the current connection status from the PLC program, the driver installs the SFC 193 (as parameterised in PLC43.INI) into the block list of ''S7-SoftPLC.'' This block can be called from the PLC-program, to monitor the hardware status.</div>Jonas
