6.4 Setting of I/O Parameters
Set the node address, I/O ports and other parameters of the of the ASEL, PSEL and SSEL controller used
for DeviceNet communication.
(1) Network type setting
I/O parameter No. 225, “Network I/F module control” has been set to “2H” (DeviceNet) at the factory. (This
parameter need not be set.)
(2) Node address
Set the node address in I/O parameter No. 226, “Network I/F module – Communication attribute 1.” The
setting range is 0 to 63. (Factory setting: 0)
(Note) If the set address is outside the above range, “D75: Fieldbus parameter error” will occur.
(3) I/O port assignments
Set the numbers of physical input/output ports of the ASEL, PSEL or SSEL used on the DeviceNet system,
as well as port assignments, in the I/O parameters specified below:
No. 1 “I/O port assignment type”
No. 14 “Network I/F module – Number of available remote input ports”
No. 15 “Network I/F module – Number of available remote output ports”
No. 16 “Network I/F module – First input port number based on mount assignment”
No. 17 “Network I/F module – First output port number based on mount assignment”
For details, refer to “List of ASEL, PSEL, SSEL network I/O parameters” on the next page.
(Note) With ASEL, PSEL and SSEL controllers, the following I/O parameters are invalid when the
DeviceNet module is used. Even if these parameters are set, they will not affect the numbers of
available DeviceNet ports, assigned port numbers, etc.
No. 2 “Standard I/O – First input port number based on mount assignment (I/O1)”
No. 3 “Standard I/O – First output port number based on mount assignment (I/O1)”
No. 10 ”Standard I/O – Error monitor”
(4) Network error monitor
Set whether or not to monitor the network using I/O parameter No. 18, “Network I/F module – Error
monitor.”
Set the error check time in bits 4 to 11 of I/O parameter No. 120, “Network attribute 1.”
A system error will generate if a network link error occurs and remains for the time set in parameter No.
120 or longer.
For details, refer to the “List of ASEL, PSEL, SSEL network I/O parameters” on the next page.
