Specifies the type of PLC to read from:
•
ControlLogix – This selection enables the full CIP supported interfaces that
provide CIP table read/write capabilities. The ControlLogix PLC family of
PLCs includes the Rockwell ControlLogix, FlexLogix, SoftLogix and other
advanced PLCs. This selection also supports numerous PLCs manufactured
by other manufacturers.
•
MicroLogix This selection provides support for Rockwell MicroLogix, SLC
and PLC-5 PLCs. These PLCs only support a limited EtherNet/IP interface
that does not include CIP table read/write support. Only Write-to-File and
Read-from-File communication that use PCCC MSG instructions is
provided.
Enter the IP address of the EtherNet/IP PLC in xxx.xxx.xxx.xxx format.
Enter the slot number of the PLC controller board. This is only required for
chassis type PLCs such as ControlLogix. For all other PLCs, set this value to 0.
The data type of the Tag or File to read from.
•
SINT – otherwise called 8 bit, or byte sized data
•
INT – otherwise called 16 bit, or WORD format
•
DINT – otherwise called 32 bit or double word format
•
BOOL – a single Boolean value
•
BIT_ARRAY – an array of Boolean values
•
FLOAT – floating point, otherwise called REAL
Specifies the EtherNet/IP PLC tag or file name. It indicates where to read the
PLC. This entry supports ASCII strings containing up to 40 characters.
File names for the PLC-5/ SLC PLCs must be in a SLC/PLC-5 file format (i.e.
N10:0, B20:0/6, etc.).
Enter the rate at which the Data Mapping process should read the configured
EtherNet/IP PLC tag or file.
If selected, the Data Mapping process will only write the received data to the
Modbus Device if:
•
The data is being received for the first time.
•
The received data has changed.
•
The previous write attempt to the Modbus Device was unsuccessful.
The Modbus Device ID to be written to.
•
If access to the Shared Memory is desired:
-
The Shared Memory must be enabled.
-
The Shared Memory device ID must be entered.
•
If a Device Id for a Modbus slave is entered, the DeviceMaster EtherNet/IP-
Modbus gateway routes the message to the appropriate location.
Select the Modbus Write function code:
•
05: Single Coil (10x) - write one coil
•
06: Single Register (40x) – write one holding register
•
15: Multiple Coils (10x) – write one or more coils
•
16: Multiple Registers (40x) – write one or more holding registers
