Characteristics and Technical Specifications of the SM 335

SM 335 – High-Speed Analog Input/Output Module for the SIMATIC S7-300
6ES7 335-7HG00-8BA1
The SM 335 only updates the relevant analog output channel when modifications
are made to the output value.
• Four activated input channels and four activated output channels with the re-
quired output, which is dependent on constantly changing values, yields a cycle
time of 1200 µs (200 µs + 4 x 200 µs + 4 x 50 µs).
• Four activated input channels and four activated output channels with un-
changed or rarely changing output values, yields a cycle time of 1000 µs
(200 µs + 4 x 200 µs + 4 x 0 µs).
• One activated input channel and four activated output channels with unchanged
or rarely changing output values, yields a cycle time of 400 µs (200 µs +
1 x 200 µs + 4 x 0 µs).
Deselecting diagnostics does not affect the cycle time.
