The only setup needed on the ET200S is the Profibus Address setting that needs to be the same as

what was entered in the Profibus Network Configuration at the beginning of the application note.

Once configurations are complete this will need to be downloaded to module via RS232 cable as

per manual.

ET200S Operation

This application note was setup to configure two digital inputs from the ET200S to go to two

internal registers in the Gateway. From there they can be radio mapped to any other Module in the

system. Also two internal register are written to the two digital outputs on the ET200 S.

The internal 4306 & 4307 (DIO #7 & 8) have been setup to write their value in to the Digital

output #1 & 2 on the ET200S.

Also the two digital inputs on the ET200S have been setup up so that their values are written into

I/O registers 4320 & 4321 (DIO # 1 & 2).

This way you get a visual ON/OFF indication on the Gateway module making it easier to establish

if communications is successful or not.

If you turn on one of the digital inputs on the Gateway (DIO7 or DIO8) this will write a value of

FFFF hex into one of the registers 4306 and 4307. These Registers are then fieldbus mapped

across to the Fieldbus area which inturn is then configured to turn on the digital outputs on the

Slave Device.

From the ET200S if you turn on any of the digital inputs a value of FFFF is read from the Slave

Device and then mapped across to registers 4320 or 4321. The DIO LEDs 1 & 2 would also be lit

on the 105U-G.

Online Diagnostics

Depending on Firmware version of the Gateway the Online Diagnostics can be done in one of two

ways. The Firmware version can be found from the module serial number located on the

underside of the module. The firmware version is written in digits 5 through 7 of the serial

number, so a module with serial number 04051709468 has firmware version 1.70

To Diagnose the Gateway whilst connected to the Profibus network this is done via the online

diagnostics whilst connected to the configuration RS232 port and using the E-series configuration

program.

For Firmware versions 1.70 or higher.

Select the Profibus Master Gateway unit in the configuration software. On the right hand side

under program unit select Diagnostics. Then in the next screen select Debug I/O.

Under Debug Options select Connect and the following screen should appear.

1 2 ... 40 41 42 43 44 45 46 47 48 49 50 ... 65 66
