6 Configuring the fieldbus network to the MC100
6.1 Connecting the MC100 and the pumps for the first time
Make sure all pumps have been giving a unique address and all the pumps have been powered up.
The FlexNet is connected to the MC100 and to the pumps in a multidrop network.
Connect SubD connector X3 to a PC using a NULL-modem cable.
Start a terminal program on the PC for example HyperTerminal.
Set the communication-parameters to: 9600 baud, 8 bits, even parity and 1 stop-bit.
When applying power to the MC100, it will identify itself by printing the line:
“ MC100 MFSC Ver. x.yy.”
(x.yy is the current version)
The MC100 will then try to identify all connected pumps on the Flexnet; the LED indicator X1 will flicker
and finally be steady green.
If for example 4 pumps holding address 1, 2, 3 and 4 are detected, the following line will be shown:
“Pumps: 1 2 3 4 1 4 4”
In this example pumps numbered 1-4 are detected, lowest number is 1 and highest number is 4 and
there are 4 pumps connected.
If the 2
nd
line is not printed and the MC12 has an alarm indication: AL01 or AL02 flashing, it must be
investigated if the FlexNet is correctly wired.
If everything is OK you continue to configure the Profibus master according to the guidelines from
HMS, please see below.
