Cyclic updating of the parameter 'Period duration'
The following representation illustrates the execution of the cyclic updating of the parameter
'Period duration'. The described workflow principle can also be used on the channels of the
high-speed counters.
①
• User sets SLOT to the required parameter
• User sets MODE_SLOT to 1
• User sets LD_SLOT to the required value (1 for period duration)
②
User changes value in SLOT continuously and technology channel evaluates continuously
③
Value in SLOT exceeds permitted limit, technology channel shows this ERR_SLOT_VAL and
continues working with the last valid value
④
Value in SLOT again in permitted range, technology channel resets ERR_SLOT_VAL inde-
pendently and continues working with the value in SLOT
⑤
User resets LD_SLOT and MODE_SLOT, technology channel continues to work with last value
