(3) How to Set Parameters
1) Settings in Common for SEL Program Communication / IAI Protocol Communication
・
Set the communication specifications for the extension SIO user release channel number to
be used. (I/O Parameter No. 100, 102, 104 and 106 “User Release Channel n Attribute 1”)
(The extension I/O slot assignment and in-board channel number assignment are already
set up at the delivery.)
(Example) When indicating User Release Channel No. 3 as the in-board channel 1 for the
extension SIO module (RS-232C) connected to Extension I/O Slot 2, and setting
to the communication specification as follows;
Baud rate : 115.2k
B
I/O Parameter 102 bit28-31=5
Data length : 8 Bits
B
I/O Parameter 102 bit24-27=8
Stop bit length : 1 Bit
B
I/O Parameter 102 bit20-23=1
Binary Classification : None
B
I/O Parameter 102 bit16-19=0
Reception Operation Classification : Reception compulsorily enabled right before sending
process
B
I/O Parameter 102 bit 8 to 11 = 0
Establish the setting as;
I/O Parameter 102 “User Release Channel 3 Attribute 1” = 58100012h
2) IAI Protocol Communication Individual Setting
A : SEL Program Communication
x
Set the way to use for the extension SIO user release channel number to be used. (I/O
Parameter 101,103,105,107 [SIO Channel 2 Opened to User] bit0-3)
(Example) When having the SEL program communication in User Release Channel
No. 2, set as I/O Parameter 101 “User Release Channel 2 Attribute 2” bit 0
to 3 = 0.
B : IAI Protocol Communication
x
Establish the setting to permit multiple channel communication for IAI protocol. (I/O
Parameter 116 [IAI Protocol Communication Attribute] bit0-3)
x
Set the way to use for the extension SIO user release channel number to be used. (I/O
Parameter 101,103,105,107 [SIO Channel 2 Opened to User] bit0-3)
x
Set the minimum response latency in IAI protocol communication. (I/O Parameter 101,
103, 105, 107 [IAI Protocol Communication Attribute] bit4-11)
x
Set the station code for the extension SIO user release channel number to be used. (I/O
Parameter 91 “User Release SIO Channel 1 Station Code”)
(* Although it is determined as User Release SIO Channel 1, this parameter is in
common for Ethernet and extension SIO.)
x
Indicate the channel available for communication with execution commands in AUTO
Mode. I/O Parameter 116 [IAI Protocol Communication Attribute] bit4-11)
