3.4 Find Connected Extension modules
When the PCI-DMC-01 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 Figure 3.4, the
second menu function (marked with 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.
Figure 3.4
If the second menu option (Scan Slave) can't find the extension modules you wish to
connect to, the "No slave found!" error message shown in Figure 3.5 will pop up. Please
check that your extension modules are all connected properly. Also check that the
expansion module is receiving power from the power supply.
