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.
