30 ppendix : pplication Examples Step 1: Set up Peer to Peer onfiguration In NetEdit, Scan Network to find your H0-EOM0. Set the Module I, IP address and Subnet Mask as appropriate for your network. In our example, we use,..0.1 and...0 respectively. In the EOM Settings tab, click the Peer to Peer onfig button. dd the evices appropriate for your project. In our example we have added three devices that are the M-GTEWY: evice 1 is the utomatic Reads table that resides in the M-GTEWY, so it is configured with the M-GTEWY IP address and the M-GEWY Unit I. evice is the first drive. It is configured with the M-GTEWY IP address and the first drive Unit I. evice is the second drive. It is configured with the M-GTEWY IP address and the second drive Unit I M-GTEWY-USER-M Hardware User Manual, 1st Ed. Rev. E 0/1-0

In our example, we use..0. and...0. lick Start Web ased onfig... To set the Gateway Modbus I as appropriate for your network. In our example, we use 1. Set the Serial Port onfiguration as appropriate for your network. For our example, we use: aud rate = 100 Parity = Odd Stop bit = 1 Step : Set the ommunication Parameters Set the communication parameters in the drives as appropriate for your network.

Slave number is the first drive and Slave number is the second drive in our example. onfigure the lines as appropriate. For our example, we will read the status registers for each drive: M-GTEWY-USER-M Hardware User Manual, 1st Ed. Rev. E 0/1 -

33 ppendix : pplication Examples Step : ccess the utomatic Read ata The ERX iox is used since the data will be read by the EOM0, rather than a serial connection M-GTEWY-USER-M Hardware User Manual, 1st Ed. Rev. E 0/1 -

34 ppendix : pplication Examples EOM0# = defined for this L program in the EOM0 iox in our Rung 1 Workspace = an internal, private register used by this iox and MUST E UNIQUE in this one instruction and MUST NOT be used anywhere else in your program. Slave I = The M-GTEWY Modbus Gateway I, 1, since we are reading the utomatic Read data stored in the M-GTEWY From Slave Element (Src) = the Gateway Memory ddress identified on the M-GTEWY Setup utomatic Reads config page. Note that the address in the M-GTEWY, 0 should be entered here as V0 and irectsoft software will change the name to T0.

35 ppendix : pplication Examples affect either the targeted address or the use of Timer 0 in the L program. Number of ytes = 0. Since our addresses for both example drives are contiguous, we can read all elements with one iox. Each element is a word, bytes, so we want to read 0 bytes to get all elements.

36 ppendix : pplication Examples Step : Read and Write from the L0 To Read data from a drive instead of using of the utomatic Read feature of the M-GTEWY, and to Write data to the drive, the Slave I in the ERX and/or EWX ioxes will be the rive I.

In our example, we will write the speed ( bytes) to the omm Speed Reference register and set the next register to RUN ( bytes) To Slave Element (est) = the Modbus register where the data will be written in the drive. In this case, V equates to P. omm Speed Reference. See GS rive manual for more details.
