5.7. Digital I/O Test
Figure 5.10
– MCS-08IO
Status
Input / Output Test: This block allows the user to check I/O status. The I/O test button is used to
test outputs as seen in this figure.
The active MCS-08IO modules are shown with their own N-Bus address block. You can follow the input and the
output status and you can switch the outputs. The I/O test property is very useful for checking the output states.
Warning: Please be careful to avoid damaging your process during the output test.
5.8. N-Bus Addressing via Setup Switch
MCS-08 systems which are energized for the first time require the N-bus addressing for each A/D Converter
module and each Digital I/O module. One way is the addressing by the xFace which is described above.
Another way is the addressing (up to address 7) via the setup switch.
Figure 5.11 – Example
Step by step manual procedure:
1. Unplug all communication cables from the Gateway Module (RS232 and BUS plug; See
GREEN ).
2. First energize the modules installed on the N-Bus.
3. Press the setup switch of the gateway module for 5 seconds. (The switch is behind the hole in the front; see
YELLOW ). The three LEDs of the gateway module ( RED ) will flash 4 times and then indicate an N-Bus
address number. You can change the address number by pressing the setup switch ( YELLOW ) slowly.
While changing the address in the Gateway module, the LEDs in the other modules ( PINK ) will change
sometimes.
