Step 5 - Transmission Of The Configuration To The Controller (S7 Plc) - Leuze electronic MA 248i Original Operating Instructions

Commissioning and configuration
A larger module is needed, for example, if a BCL bar code scanner is to be configured by
means of PT-sequences, or an RFID transponder is to be described. In these cases, larger
data modules are usually sensible.
Examples of sensible settings for corresponding Leuze devices
BPS 8 and BPS 300i
• Input module: 8 bytes
• Output module: 4 bytes
Hand-held scanner
• Input module: individual
The size of the input module is dependent on the number of digits of the bar code or
2D code that is to be read. For example, with an 12-digit bar code (+ 2 bytes of status
bytes), the input module with 16 bytes is sensible.
• Output module: none
Because the hand-held scanner does not typically send any data, no output module
is necessary.
BCL bar code scanners, RFID devices (RFM, RFI and RFU), LSIS 222 and DCR 202i
• Input module: individual
The size of the input module is dependent on the number of digits of the bar code,
RFID code or 2D code that is to be read. For example, with an 18-digit bar code
(+ 2 bytes of status bytes), the input module with 20 bytes is sensible.
• Output module: 4 bytes
12.3.5 Step 5 – Transmission of the configuration to the controller (S7 PLC)
After correct transmission to the controller (S7 PLC), the PLC automatically carries out the
following activities:
• Check device names
• Assignment of the IP addresses that were configured in the HW Config to the
IO devices
• Establishment of a connection between the controller and configured IO devices
• Cyclical data exchange
