CREADREG: Continuous register reading
Parameter description
NODEADDR
Identifies the node address within the target segment.
The parameter can be specified as direct address, located variable, unlocated
variable or literal.
ROUTPATH
Identifies the routing path to the target segment. The two-digit information units run
from 01 … 64 (see Function mode, p. 24). If the slave resides in the local network
segment, ROUTPATH must be set to "0" or must be left unconnected.
The parameter can be specified as direct address, located variable, unlocated
variable or literal.
SLAVEREG
Start of the area in the addressed slave from which the source data are read. The
source area always resides within the 4x register area. SLAVEREG expects the
source address as offset within the 4x area. The initial "4" must be omitted (e.g. 59
(contents of the variable or value of the literal) = 40059).
The parameter can be specified as direct address, located variable, unlocated
variable or literal.
NO_REG
Number of registers to be read from slave processor (1 ... 100).
The parameter can be specified as direct address, located variable, unlocated
variable or literal.
STATUS
Error code, see Runtime errors, p. 95
The parameter can be specified as direct address, located variable or unlocated
variable.
REG_READ
This word parameter addresses the first register in a series of NO_REG successive
registers used as destination data area.
The parameter must be entered as a direct address or located variable.
