Communications cycle time setting (ms)

Name	Range	Details
Communications	0000 to 01F4 Hex	Sets the communications cycle time in milli-
Cycle Time Set-	(0 to 500)	seconds. Setting range: 0 to 500 ms
ting		If this bit is set to 0, the optimum time calcu-
		lated by the Unit will be used. If a value
		higher than 500 ms is set, then the Unit will
		operate at 500 ms.
		If the setting cannot be correctly made for
		some reason, the Scan List Register/Clear
		Failed Flag (word n+12, bit 11) in Master Sta-
		tus 1 and the Temporary Setting Switch for
		Communications Cycle Time (word n, bit 12)
		will be turned OFF.

Note If the setting is smaller than the optimum communications cycle time calcu- lated by the Unit and stored internally in the Unit, then the value calculated by the Unit will be used.
