A maximum of 512 I/O points on I/O Units can be connected per Master, i.e.,
when the I/O Link Units are all set for 16 points each, up to 32 Units can be con-
nected to one Master on a C500. This would mean, however, that all I/O points
provided by the PC would be occupied and that no other I/O Units could be con-
nected. (The C20 I/O Link Unit has no setting for the number of I/O points and is
thus limited to 32 points.)

Up to two Slaves can be connected to one Master. Each I/O Link Unit requires 16
or 32 points (depending on the setting) and each Optical I/O Unit requires eight
points. These may be used in any combination of I/O which does not exceed the
total number of I/O points provided by the PC to which the Master is connected.
If more than 32 Units are connected to the same Master, a Repeater Unit must
be installed after the first 32 Units. The Slave's I/O Units are not counted in the 32
Units, but the I/O points must be included in the total number of I/O points.
