I/O byte No. setting
When
SL-GU1-D
is incorporated into the DeviceNet system, the data exchange size on De-
viceNet is determined by the setting on the
S-LINK
system side.
Secure a memory area on the master depending on the total No. of I/O, I/O setting and sta-
tus setting of the
S-LINK
system side.

Example: In case of
S-LINK
I/O units = 128 Nos., input: 64 Nos., output: 64 Nos., and with status added
Required No. of bytes for input data = 10 bytes
Required No. of bytes for output data = 8 bytes
16. MEMORY MAP
Transmission / Reception I/O data, status data
\ * }
lowest address (00H), is as given below
Reception I/O data area : Input data area + Status data area
Transmission I/O data area: Output data area
I/O data assignment for S-LINK unit address
The
S-LINK
addresses are organized linearly and each
S-LINK
unit can be assigned I/O set-
ting in units of 32.
Further, the upper level transmission / reception I/O data is divided into input data and output
data, assigned and transmitted, and organized continuously from the lowest position.
As an example, the memory assignment for the case of I/O channels: 128 Nos., input setting:
Address 0 to 63, output setting: Address 64 to 127, and with status data is shown below.
(In this case, the upper side data size is input: 10 bytes, output: 8 bytes.)
