cyclic– isochronous● Rated input voltage 24 VDC● Nonisolated to the CPU● Fast Mode selectable; with faster transducer action and compressed feedback interface.
The Fast Mode is available from firmware version V2.0.0 in SM 338; POS-INPUT and can
be selected from STEP 7 V5.3+SP2.
Supported encoder types
Encoder types supported by SM 338; POS-INPUT:● Absolute value encoder (SSI), frame length 13 bit● Absolute value encoder (SSI), frame length 21 bit● Absolute value encoder (SSI), frame length 25 bitSupported data formatsSM 338; POS-INPUT supports gray code and binary code.
To extend functions and for troubleshooting, it is possible with the help of STEP 7 HWConfig
to load firmware updates in the operating system memory of the SM 338; POSINPUT.
Note
When you boot the firmware update, the old firmware is deleted. If the firmware update is
interrupted or terminated for some reason, thereafter the SM 338; POS-INPUT ceases to
function properly. Reboot the firmware update and wait until this has completed successfully.
Note
The firmware update is only possible in remote operation if the header assembly (slavecircuit) employed supports the system services required for this.7.4.1 Isochronous modeNoteFor basic information on isochronous mode, refer to the SIMATIC; isochronous mode
function manual.
Hardware requirements
To operate SM 338 in isochronous mode, you need:● a CPU which supports isochronous mode● a DP master which supports the constant bus cycle● a slave interface (IM 153-x) which supports isochronous mode
Properties
SM 338 operates in non-isochronous or isochronous mode, depending on system
parameters.
In isochronous mode, data are exchanged between the DP master and SM 338 in
synchronism to the PROFIBUS DP cycle.
In isochronous mode, all 16 bytes of the feedback interface are consistent.
If synchronism is lost due to disturbance or failure/delay of Global Control (GC), the SM 338
resumes isochronous mode at the next cycle without error reaction.
If synchronism is lost, the feedback interface is not updated
Important rules to observe wiring the module:● Ground of the encoder supply is connected to CPU ground potential. Thus, establish a
low impedance connection between pin 2 of SM 338 (M) and CPU ground.
 Always use shielded twisted-pair cable to wire encoder signals (pins 3 to 14.) Connect
both ends of the shielding.
Use the shield connection element to terminate the shielding on SM 338 (order number
6ES7390-5AA00-0AA0).● Connect an external power supply if the maximum output current (900 mA) of the encoder
supply is exceeded.
The absolute value encoder transfers its values in frames to the SM 338. The SM 338
initiates the frame transfer.
