Operand Description
(U) Start I/O number (first three digits in four-digit hexadecimal
representation) of a module
(s) Switching the mode
• 0: Shift to normal mode (normal output mode)
• 1: Shift to offset/gain setting mode
Setting a value outside the above range results in "Shift to
offset/gain setting mode".
EN Execution condition
ENO Execution result
*1 The mode name differs depending on the module used: normal output mode for the R60DA4, R60DAV8, R60DAI8, and R60DAH4 and
normal mode for other analog modules.
