●
"Baudrate"
Set the data baud rate for the network here. The baud rate is determined by the slowest
HMI device connected to the network. Possible baud rates for the HMI devices
OP 73micro and TP 177micro:
–
9.6 Kbps
–
19.2 Kbps
–
187.5 Kbps
The setting must be identical throughout the network.
●
"Address"
Set the address of the HMI device here. The address must be unique within the network.
●
"Only master on the bus"
na
Network parameters
In the "Network" tab, set the parameters of the network which contains the HMI device.
●
"Profile"
Set "MPI" here.
Select "DP" if you need a baud rate of 9.6 Kbps.
●
"Highest station address"
Set the highest station address. The highest station address must be equal to or higher
than the highest actual address. The setting must be identical throughout the network.
●
"Number of masters"
Set the number of masters operating in the network. HMI devices must be operated in
master mode. The S7-200 may be operated in master mode.
Communication partners
Under "PLC", assign an address to the S7-200 which is to communicate with the HMI device.
●
"Address"
Here, set the address of the S7 module (CPU) that is connected to the HMI device.
●
"Slot"
This parameter is not necessary.
●
"Rack"
This parameter is not necessary.
●
"Cyclic operation"
This parameter is not necessary.
Addressing the SIMATIC S7 PLC
The address of your S7-200 PLC is configured using the STEP 7 MicroWIN tool.
