Digital signal name is available for the external log-
ic inputs that are connected.
Ater selecting the menu entry “External input 1 — 6” and subsequently press-
ing the key, a character string can be entered that will identify the input.
This identification is shown in different graphical representations on the re-
corder.
Sampling cycle The external logic inputs are registered by the recorder with a maximum delay
of 1 second.
4.4 External counters
The two inputs (external counters 1 — 2) are a special feature. They are in-
tended for connection to the counter outputs of two mTRON analog input
modules. Each counter contains the result of a hardware pulse counter of the
Neuron firmware for two cycles of the mTRON analog input module (one cycle
= 420msec) and has 16 bit (without sign). Up to 65535 pulses in 840msec can
be counted in this way.
The counters are configured via the menu Configuration
