Ethernet Communications
The following example illustrates how data is written using no-protocol communications. In this example,
1,500 words of data starting from register IW07800 in the local station are written to registers starting at
MW0800000 in the remote station.
PARAM22
Local Station Register
Type
Set the register type (M, G, I, O, or S) of the data to be written that is
stored in the local station.
PARAM24 For system use
Set this parameter to 0 from a user program or by other means in the
first scan after the power is turned ON. Thereafter, do not change the
value of this parameter. This parameter is used by the system.
1. The registers in the remote station are specified by the M Register Writing Range Low parameter in
the MSG-RCVE function.
2. Set the address of the registers to write to within the range specified by the M Register Writing
Range Low and M Register Writing Range High parameters in the MSG-RCVE function. Data will
not be written if an address exceeds the valid setting range.
