6.3 REMOTE DIGITAL INPUT MODULE BLOCK (RDIM)
The remote digital input module block is used to input as many as 16 digital inputs from a
remote digital input module connected to a CS-31 remote I/O network. The RDIM block is
valid for use with the following remote modules:
Module No. Type Description
ICSI 08 D1 Input 8 Non-isolated 24VDC input channels
ICSI 08 E1 Input 8 Isolated 24VDC input channels
ICSI 08 E3 Input 8 Isolated 120VDC input channels
ICSI 08 E4 Input 8 Isolated 230VDC input channels
ICSI 16 D1 Input 16 Non-isolated 24VDC input channels
ICSI 16 E1 Input 16 Isolated 24VDC input channels
ICSK 20 F1 Input/Output 12 non-isolated 24VDC input channels and 8
isolated relay output channels
ICSC 08 L1 Input/Output 8 user-configurable channels for 24VDC input
or 24VDC 500mA transistor output
The RDIM block receives the inputs from the CS-31 bus via a Remote I/O Interface (RIO)
Module installed in the instrument. The instrument database must have one RDIM block for
each remote digital input module on the CS-31 bus. The RDIM can be connected using the
RIO block MODOUT to this blocks MODIN connection.
Block outputs are the data, data quality, and active and unacknowledged status of the block’s
diagnostic error. A functional block diagram of an RDIM block is shown in Figure 6-4. Two of
the menus used to configure the block are shown in Figure 6-5 and Figure 6-6.
