Omron CJ1W-CLK21-V1 Reception Processing, Number of words transferred ⋅ 0.00075 + 1.3 ms

Message Delay Times		Section 8-4
	Reception Processing
	Number of words transferred ⋅ 0.00075 + 1.3 ms
Note The I/O response time can increase due to noise or restrictions on the number
	of frames that can be transmitted while data links are operating.
	Example
	In this example, the maximum transmission delay is calculated for an instruc-
	tion sending 256 words of data in a system with 32 nodes. Network specifics
	are detailed below:
	Baud rate:	2 Mbps
	Max. node address:	32
	Number of nodes:	32
	Number of polled nodes per comm cycle: 4
	Source node execution:	Synchronous
	Destination node execution:	Asynchronous
	Number of words:	256
	Data link:	Inactive
	Link servicing interval (source node)	PLC cycle time (source node)
	Link service processing (source node)	1 ms
	Transmission processing	0.00075 ⋅ 256 + 2 = 2.192 ≅
		2.2 ms
	Communications cycle time (See note.)	600 ⋅ 4 + 110 ⋅ 32 + 320 ⋅ 0 + 4 ⋅
		0 + 2,290 = 8,210 ∝s ≅ 8.2 ms
	Transmission delay	0.008 ⋅ 256 + 0.112 = 2.16 ≅
		2.2 ms
	Reception processing	0.00075 ⋅ 256 + 1.13 = 1.492 ≅
		1.5 ms
	Link servicing interval (destination node)	As required by Programming
		Device
	Link service processing (destination node)	1 ms
	Total (max. transmission delay)	PLC cycle time (source node) +
		Peripheral servicing interval
		(destination node) + 16.1 ms
Note
	This communications cycle time is calculated assuming that there is no node
	that transmits event frames before the SEND command is sent.
RECV Instruction	The data flow which will yield the maximum transfer interval from the time the
Maximum Delay Time	RECV(193)/RECV(98) instruction is executed by the user program to the time
	the Controller Link Unit stores the data in the local Unit’s memory area is
	described below.
Note	Be sure to take into account the time required for data links and program exe-
	cution, which are not included in the following example.
