SSI-interface
The UNIGATE also supports the connection of applications or products, that communicate via
SSI.
6.1
Initiation of the SSI-interface
The required Script (example_SSI), the firmware- (Cust0023) and Protocol Developer-extension
(Cust_ssi.xml) are available free of charge from our website at www.deutschmann.de, as well as
the softwaretool Protocol Developer and the configuration software WINGATE.
•
In the Protocol Developer (see chapter 7, The Debug-interface) the ConfigFile "Cust_ssi.xml"
has to be added. At Options -> Settings -> ConfigFiles.
•
Load the Script "example_SSI.dss" into the Protocol Developer.
•
The encoder type has to be defined in the Script itself under "Set number of bits" and "Set
typ" (default = 12-Bit-Single-Turn-Gray):
// Set number of bits (1..16 = Single Turn, 17..32 = Multi Turn)
moveconst (bAnzBit, 12); // i.e. 12 Bit single turn
// Set typ
// Values of bTyp:
// 0 = Reserved
// 1 = Output-value without change (i.e. binary encoder)
// 2 = Output-value changed from Gray to Binary (i.e. Gray encoder)
// >2 = Reserved
moveconst ( wTyp, 2); // i.e. 12 Bit Gray
•
Load the Script into the device. Open WINGATE and activate the device in the configuation
mode (see chapter 4.1, Configuration mode (config mode)) - an actuation message appears,
that looks in line with the following (example CL-PB):
Special Firmware (23) not loaded
RS-PBV1-CL (232/422/485) V7.31[30] (c)dA Switch=0x02FF Script(8k)="SSI" Aut-
hor="Deutschmann Automation" Version="V 1.0" Date=20.03.2008 SN=47110002 ID=2
Konfigmode...
The note "Special Firmware (23) not loaded" means that the firmware-extension is not yet
loaded. The extension is loaded through Extras -> Firmware Script Extension. Select the file
"Cust0023 (Cmd 23 + 24 for SSI).hex" and choose "write extension".
•
Re-start the device -> now only the device’s actual actuation message appears and not the
note any more.
•
Bring the device into the data exchange mode (see chapter 4.3, Data exchange mode) ->
DONE!
6.2
Hardware-wiring
The clock wires of the SSI-interface are placed onto the Tx-wires of the RS422-interface and the
data wires onto the Rx-wires at the UNIGATE CL.
