Shared Memory Configuration Page (Continued)
Indicates which master(s) have write access to the Shared Memory
block.
All (Except Class1) – Except for Class1 connections, all Modbus
•
masters, Modbus Object and Data Mapping functions have write
access to the block.
• Port specific serial master:
Port-1
-
Port-2 (2-port and 4-port models only)
-
Port-3 (4-port models only)
-
Port-4 (4-port models only)
-
Modbus/TCP - Modbus/TCP master(s) at a specified IP address
•
Ethernet TCP/IP – Ethernet TCP/IP master(s) at a specified IP
•
address
EIP Class1 – EtherNet/IP Class1 connection. Only one EtherNet/IP
•
Class connection can access the block at one time.
EIP TAG/FILE – Tag/File to Modbus configurations at a specified
•
IP address
EIP Modbus Object – Messages via the Modbus Object from an
•
EtherNet/IP controller at a specified IP address
Modbus to Modbus – Modbus to Modbus configuration(s)
•
IP address of the Modbus/TCP master, Ethernet TCP/IP master or
EtherNet/IP controller. Zeros indicate that there is no configuration.
Note: Does not apply to All (Except Class1), port-specific serial
masters, Class1, or Modbus to Modbus configuration(s)..
User-defined description of the Shared Memory block. ASCII string
with a maximum of 80 characters in length.
Specifies the block number.
Specifies the coil range.
If selected, the Shared Memory block(s) accept broadcast messages
from Modbus masters addressed to their memory block(s).
If selected, the Shared Memory block is added to the Class1 to the
Active Rx Class 1 Configuration.
If selected, the Data Mapping process performs writes to this Shared
Memory block only when there is an active Class1 read connection to
this block.
If selected, the Shared Memory block's data is cleared when all Class1
connections to this block are lost.
