4 Overview
This is the basic configuration. As it can be seen in the figure below, the digital I/O modules
used in the system are dragged and dropped to the main base unit where they are located.

KI00347B 2014-04
Choose the project profile, in this case the basic is being used.
In the Basic project profile, the application has a user task from the Freewheeling type called
MainTask which executes the program in a continuous loop (with no definition of cycle time)
with priority fixed in 13. This task is responsible for the execution of a single programming
unit POU called MainPrg. It is important to stress that the cycle time can vary according with
communication task quantity used, as in this mode, the main task is interrupted by
communication tasks.
This profile allows the inclusion of two interruption tasks with higher priority which can
preempt the MainTask at any moment: the task called ExternInterruptTask00 is an
interruption task from the Extern type with priority fixed in 02; the task called
TimeInterruptTask00 is an interruption task from the cyclic type with priority fixed in 1.

6.4 Configuration in BCS Tools
To make settings and connect variables to the inputs double click the module in the
hardware configuration view.
Noise Suppresion Filter = Set the filter to the frequency used in your country. Keep in mind
that enabling the Noise Suppression Filter includes a delay per input. Consult User’s manual
for more details.
Input XX
Type = Set the signal type.
Min/Max Value = Valid input is-30000 – 30000. The engineering value can be set but keep
in mind that the output signal is of INT type, therefore any decimals will be truncated.
Recommended setting is 0 – 30000 and then use a scaling function in the program code.
To achieve the highest possible resolution use -30000 – 30000.
Digital Filter = Digital filter enabling a delay of the input.
Open Loop value = When the module detects a open loop a specific value and behaviour can
be set.
KI_eng.dot, 070221
Alarms = Alarms can be generated by the module using user defined thresholds. Each
threshold has a specific diagnostic bit that will be set when the alarm is active. Consult
User’s manual for more details.

Configuration in BCS Tools
To make settings and connect variables to the analog outputs double click the module in the
hardware configuration view.
Output XX
Type = Set the signal type.
Min/Max Value = Valid input is-30000 – 30000. The engineering value can be set but keep
in mind that the output signal is of INT type, therefore any decimals will be truncated.
Recommended setting is 0 – 30000 and then use a scaling function in the program code.
To achieve the highest possible resolution use -30000 – 30000.
Output behaviour on CPU Stop Mode = When the cpu is in STOP mode a user value can
be set for the output by setting this option to TRUE.
User defined output value = The output value when the user defined output value has been
enabled.

9 Troubleshooting
To troubleshoot and get diagnostics from the Nexto system there are several possibilities
available.

Diagnostics structures, created automaticly in BCS Tools.

The OTD, One Touch Diagnostics function and LED:s on the NX5001 module.

Diagnostics via the WWW page in the cpu.
9.1 Diagnostic structures
When the modules are inserted a data structure is created automaticly located in a list named
Diagnostics. This list will be populated with diagnostics structures for all hardware inserted
in BCS Tools.
KI_eng.dot, 070221
In this case there is a Open loop in channel 1 of the NX6000 module.

KI00347B 2014-04
9.2 OTD and LED information
All modules in a Nexto system has a display. The 0 and 1 to the left of the display are used
for grouping the I/O:s and the 0 – 7 to the right are indicators for the input or output signal.
KI_eng.dot, 070221
The D and E led are common to all modules.
www.beijer.se
21 (26)
KI00347B 2014-04
When there is diagnostics available the letter D will blink on the display and the cpu will
display the number of diagnostic messages available and the DG led will blink 2x fast
CPU and NX5001 display.
DG 1 indicates that there is one diagnostic message available.
To check the diagnostic message in the display just press the OTD button on the I/O
module, located on the top of the module.
Diagnostic
KI_eng.dot, 070221
The diagnostics available will be displayed according to the following flowchart.
