•
timer
•
conditionally switched counter
Optional function configuration of counter No. 2 and 4 inputs:
•
incremental position encoder (traces are shifted about 90°)
•
pulses and direction
•
up and down
•
period measurement
Programmable functions of counter No. 1 and 3 outputs:
•
manual output control by OUT0, OUT1 bits
•
digital mark mode (output is switched on on interval of two defined points)
•
positioning up/down by outputs
(DO0 - up, DO1 - down)
•
moving to reference point by outputs up/down (DO0 - up, DO1 - down)
•
positioning up, 2 speeds
(DO0 - fast, DO1 - slowly)
•
positioning down, 2 speeds
(DO0 - fast, DO1 - slowly)
•
moving to reference point, 2 speeds
(DO0 - fast, DO1 - slowly)
Notice: Moving direction for two speed level control is controlled by program using
common binary output.

7. DIAGNOSTICS
The basic diagnostic system of the module is part of the standard module software. The
diagnostic system becomes active after module power supply is on, and works independently
from the user. The error states of the module being diagnosed are passed on the central
module of the assembly and displayed on the module panel. Besides the errors of the module
itself, the state of protection circuits of the outputs is passed at the status.
