■Description, data type of result
Setting data Description
(D) Start device No. which stores the reading data.
(S1) RIO Axis No. of the target SSCNET/H head module (601 to 608)
(S2) First I/O No. of the intelligent function module which data to be read are stored.
(00 to FEH: First 2 digits when I/O No. is 3 digits)
(S3) First address of the buffer memory of the intelligent function module which stores the data to be read.
(n) Number of words to be read (1 to 32767)
(D1) Complete devices
(D1+0): Self CPU device is made to turn ON by the reading completion.
(D1+1): Self CPU device is made to turn ON by the reading abnormal completion. ("D1+0" also turns ON at the
abnormal completion)
Processing details
