ms ticker
Some I/O compound modules are provided with an integrated
ms−ticker for the logging of states. The ms−ticker works with a
resolution of 1
ms, counts from 0 ... 65535 ms after power−on and
then starts with 0 again.
Time stamp By means of the time stamp function, initial states, together
with a time value (see
ms−ticker) and a consecutive number, can
be transferred to the FIFO memory as a time stamp entry.
PWM Pulse width modulation
SSI interface For direct connection of the I/O system to an SSI encoder
(EPM−S604)
Basic error limit Accuracy of analog I/Os at 25 °C relating to the upper limit of
effective range (according to EN61131);
example: measuring range = 0 ... 10 V or −10 V ... +10 V; basic
error limit =
±0.2 % ® 10 V * 0.2/100 = 20 mV; this means that at
25 °C a maximum measuring error of ±20 mV can occur.
Operational error limit Accuracy of analog I/Os across the entire admissible temperature
range for the module relating to the upper limit of effective
range (according to EN61131).
Basic conversion time Time required by an A/D converter to record the measured value.
