Finding Connected Expansion Modules

When the PCI-DMC-A01 card has been found and marked, this means that the serial
communications link has been established. The next step is to scan and see how many
connected modules are linked in series on the same Ring. As shown in Fig. 3.4, the second
menu function (marked with a bracket) is Scan Slave. You can use it to find the available and
working modules on the Ring as well as the properties of these connected modules.
If the second menu option (Scan Slave) is unable to find the expansion modules you wish to
connect to, the "No slave found!" error message shown in Fig. 3.5 will pop up. Please check
that your expansion modules are all connected properly. Also check that the expansion
module is receiving power from the power supply.
