INSTALLATION
The maximum length of the Pro-N device - module link is:
2 m for MRI module (max one module)
20 m for MMOS-4 module (max one MMI module)
30 m for MID16 and MPT modules
2 m for MPT module (max one Pt100 module)
2 m for MCI module (max one current converter module)
For upgrading, that may be operated at any time with in service devices too, the following operations
must be performed:
Turn OFF power supply
Connect the auxiliary modules to the Thybus port in daisy chain mode following the INPUT-OUTPUT
sequence.
[1]
If two MID16 (binary inputs) are installed, the hardware address must be set to avoid communica-
tion collisions on the Thybus; for this purpose the default address must be changed on one module,
by means of dip-switch on the top circuit board (front plate must be removed).
Turn on power
Go on to the sw setting (see SETTING section of instruction manual).
Note 1 The insertion order is free.
One MRI module, two MID16 modules, one MPT module, one MCI module and one MMI module (separate operator panel) can be connect at the
same time to the Thybus port (maximum expansion).
