1. Messages asynchronously reads or writes a block of data to another module on a network. Controller communication done using local or remote messages. local messaging is accessible without a separate device acting as a bridge. Remote messages use a remote network, where devices are accessible by passing or routing through a device to another network.

2. Message Elements The message file uses 24 different elements to control several aspects of the message. Some elements are: – Address (Bridge and Node) – Type – Channel and Target # – Time Out information – Other Control Parameters

3. PLC5 Message

4. 1. PLC5 to PLC5 on the same network (Local) 2. PLC5 to PLC5 on different networks (Remote) 3. SoftLogix 5800 to PLC5 (MSG Instruction) 4. SoftLogix 5800 to SoftLogix 5800 (Produced/Consumed tags). Communication Labs

5. Omron and Siemens PLC cannot send data directly protocols used to transmit data via Ethernet is different It can be done by using a PC with software that translates protocols example is RSView32 or Studio with 2 OPC Server or a 3rd party hardware Gateway. (Anybus-X) Communication with Non- AB Controllers

6. DH+ is a token ring network with a maximum of 63 nodes.(octal) a device that has the token sends the data and gives the token to the next highest node on the network Cable is Belden (Blue Hose) with 1 twisted and shielded pair of conductors, daisy chaining the processors together. each device needs to have a unique address on that network DH+ Networking

7. PLC5 to PLC5 on the same network

8. Settings In the PLC5 you can use a MG file as a control address You have to configure whether you want to read from another processor or write to one. we only have 1 port on the PLC 5/11 In the box with the control bits, the Continuous Run bit is set to one.

9. local or remote is selected. Remote is used when sending a message between different networksSettings

10. Concerns Should never directly control IO over a communication network. Danger of that is that if the network fails, you have no control over the outputs anymore and it will remain in it’s last state.

11. DHRIO Card Routing Table:

13. DHRIO card with the 2 channels it has. Those channels are electrically completely separate Each of the channels has to have a DH+ node address. In the classroom Channel A is 70 and channel B is 71. network has to have an address. In the case of a network we call that a Link ID

14. Selecting network type and node address switches
