1) Using digital I/O modules PCD2.E16x or A46x with 16 I/Os each

2) On all PCD2s, address 255 is reserved for the watchdog; on the M170, address 511 is also reserved for this

purpose. The I/Os reserved for the watchdog cannot be used by the user, and no analogue or H modules may be

attached to sockets with base address 240 (and on the M170, 496 also)

3) Not all PCD4 I/O modules are suitable for use with PCD2 CPUs; please refer to the section on “Expansion with

PCD4 components”

4) Typical values; the processing time is dependent on the load on the communication ports
