A maximum of 512 I/O points on I/O Link 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 C200H. (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 C500 Slaves, either optical or wired, can be connected to the C200H
PC (regardless of the number of C200H Masters). C500 Slaves and C200H
Slaves can also be used in combination; however, a maximum of five Slaves can
be attached, with each C500 Slave counted as two Slaves. Any Wired Slaves
must be counted in the total. Here, Special I/O Units can be mounted to C500
