6.6.5. Special outputs

The special outputs are divided into analog and digital signals:

6.6.5.1. Special outputs digital

- Safty output/RUN-Control:

To have the possibility to control the CamCon even in cases of short circuits in

the control channels or errors of the Measuring System, a rotating cam can be

programmed for a single cam output. This output is only switched of if an error

occurs and can therefore be used as a safety output.

If the programming changes, the safety output will be reset. See also chapter

"6.6.6. System upgrading" on page 47.

A "0" in the input box means that no safety output has been programmed.

- Send position The CamCon provides the opportunity to put the actual value directly and in

real time onto the outputs.

This option is used for devices like the DC300 or the 1756-DICAM as well as

for the Profibus configuration CP16/P to have the actual value in real time

available for a PLC.

You can choose between four different settings:

"no" = Actual value is not put out.

"Gray" = Actual value is put out as a gray code on the outputs (physical value).

"Binary" = Actual value is put out in binary code for a DC300, 1756-DICAM and CP16/P.

(displayed value includes factor, offset and direction of turn).

"Exp." = Actual value is put out as a gray code only with CamCon DC115 for a Master -

Slave - Connection.

With this function, the lowest value bit is counted first the others follow later

(actual value of 32 bits) behind the last defined output.

Example 1: For a CamCon with e.g. 32 hardware outputs, this is output 33. If the actual

value shall be available at the 24V-outputs, the number of defined hardware

outputs has to be reduced to e.g. 16, to have the first 16 Bit of the actual value

on outputs 17-24.

Example 2: For a CamCon DC300 or 1756-DICAM with 24b hardware outputs and 16

virtual inputs via the back plane this is e.g. the virtual backplane output 41.

- Direction output: You can set a cam output that displays the direction of the machine’s

movement or rotation.

For a positive movement or rotation, the cam output is switched on, for a

negative it is switched off.

Note: If the direction of movement changes, the output can only be switched if the

threshold set in "Direction hysteresis" is exceeded.
