Operating Instructions, 02/2022, J31069-D0176-U001-A6-7618
The coiled connecting cable of the optical handheld readers SIMATIC MV320 has a length of
1.6 m. Due to its coiling, it can be extended to a length of 4 m during operation. A
preassembled cable is also available for connection of the SIMATIC RF1040R/RF1070R
readers.
When connecting general serial devices, you need to assemble the cable yourself for the
specific device. You will find detailed information on this topic in section “Custom assembled
connecting cables (Page 58)“.
Power supply
The connected field device can be supplied with power via the communications module if the
performance data of the RF170C is not exceeded. Note the technical specifications of the
RF170C in this respect: 24 V max. 0.8 A or 5 V max. 1.2 A.
A.2.3
Hardware configuration
The optical handheld readers and access control readers can be integrated in SIMATIC
automation systems with the aid of STEP 7 Basic / Professional (TIA Portal) or STEP 7 Classic
(SIMATIC Manager). The connection is via the ET 200 pro module.
Below the configuration via the TIA Portal is described. Information on configuring other
serial devices is available in the respective manuals.
Requirement
The optical handheld reader / the RF1040R/RF1070R is connected to the controller via the
RF170C RS-422/RS-232 and has started up. The TIA Portal has been started. You have created
a project.
Procedure
Proceed as follows to configure the communications module:
1.
In the module parameters of the RF170C select the suitable MOBY mode:
–
for SIMATIC MV320 (≲ AS 2):
MV3xx
–
for SIMATIC MV320 (≥ AS 3) and SIMATIC RF1070R: Freeport protocol
–
for other serial devices Freeport protocol
NOTICE
Changing to the RS-232 interface
By selecting “MV3xx”, the communications module automatically switches to the RS-232
interface. If you select the Freeport protocol, you need to change the interface to RS-232
manually and set the interface parameters.
2.
Select the user mode "FB 45 / FC 45" or "Ident profile".
