Item Applicable data
Input parameters Values (See note 1.), addresses, and program symbols (glo-
bal symbols and local symbols) (See note 2.)
Note The data that is passed to the input variable from the
parameter is the actual value of the size of the input
variable data. (An address itself will not be passed even
if an address is set in the parameter.)
Note Input parameters must be set. If even one input param-
eter has not been set, a fatal error will occur and the
input parameters will not be transferred to the actual
PLC.
Output parameters Addresses, program symbols (global symbols, local symbols)
(See note 2.)
