3.5Communication times
The time required for communication can be displayed as a sequence of processing steps (with corresponding times).
Step |
Explanation |
t0 |
User program in host starts request to the controller (e.g. controller enable with C0040=1) |
t1 |
Software driver (e.g. LECOM-S5) in host converts request data into LECOM-A/B protocol V2.0 and starts the transmission. |
|
|
t2 |
Serial data transfer to the controller (telegram time) |
t3 |
Data receipt of the controller: Processing of request and start of response |
|
|
t4 |
Response data to host are being transmitted (telegram time) |
t5 |
Software driver in host evaluates the response, i.e. the response is converted into the format of the user program. |
t6 |
Application program in host gets the result |
The time sections t2, t4 and t3 are described in detail in the following:
Telegram time (t2 + t4)
The telegram time comprises the serial communication from the host to the controller (t2) and the corresponding response from the controller (t4). The time depends on the telegram type and the baud rate set under C0125.

1)35 ms is valid for C0001 = 3. If C0001 = 1 and you write under C0046, access is also possible. However, the processing time is prolonged to 70 ms.
2)For immediately following write-access procedures, the response times may be up to 50ms.
3)The code number C0046 can only be read. Use a free code number (e. g. C0141) to select a setpoint. For this, refer to the 93XX Manual.
4)This is a typical value. For some codes, the processing times may be longer. For this, refer to the 93XX Manual.

Installation
4.2Mechanical installation
•Remove the keypad from the front of the controller if it is attached.
•Attach the 2101 fieldbus module to the front of the controller. Use the fixing screw, which is part of the delivery package, to secure the fieldbus module (see Fig. 4-1, pos. 3) ( 1-1).
Stop!
Tighten the fixing screw to ensure adequate PE connection of the 2102 fieldbus module.
4.3Electrical installation
•The communication of controllers 820X and 821X may be disturbed by electromagnetic radiation. Use an additional PE cable to ensure safe communication (see Fig. 4-1 pos. 13). This is not necessary with the controllers 822X and 93XX.
Caution!
The bus system continues operation even if the 2102 fieldbus system is disconnected from the power supply because of an error.
If this is the case, the controller cannot be reached by the host.
Stop!
The polarity of the voltage supply must not be reversed, otherwise, the 2102 fieldbus module will be destroyed !
•Voltage supply:
–external 24 V (15 to 30 V) via plug-in connectors 39 (-) / 59 (+) or
–internal via the controller (connection by plugging it on).
With 820X it is not possible to have an internal voltage supply via the controller.

Note!
Internal voltage supply of the fieldbus module connected to a 8200 vector
Controllers with an extended AIF interface (front of the 8200 vector) can be internally supplied. The part of the drawing highlighted with grey shows the jumper position.
In Lenze setting, the fieldbus module is not internally supplied.
For internal voltage supply, put the jumper in the position indicated below.

4.4Wiring to a host
This chapter informs you about networking the 2102 fieldbus module using the bus systems RS232 (LECOM-A), RS485 (LECOM-B) or optical fibres (LECOM-LI).
The accessories requires are listed in chapter 8.1.
Danger!
•An additional electrical isolation is required if
–a 820X, 821X or 8200 vector controller will be connected to a host
–a safe electrical isolation (double basic insulation) to VDE 0160 is required.
•Please observe the following:
–RS232:
The electrical isolation of the RS232 interface (LECOM-A) can be achieved by two 2101IB level converters or another RS232 electrical isolation.
–RS485:
With RS485 (LECOM-B), the 2101IB level converter should be installed to the host if it is not equipped with an appropriately isolated interface.
–Optical fibres:
If two controllers are connected via optical fibres (LECOM-LI) they are always isolated.
•For wiring, the electrical isolation of the supply voltage must be taken into account.
The controllers 822X and 93XX are equipped with a double basic insulation to VDE 0160, additional electrical isolation is therefore not necessary.

Connection to the host (PC/PLC) |
Connection between two controllers (cable 1 in Fig. 4-4):
•Connect the cable shield with terminal 89 (direct PE) of one fieldbus module and terminal 88 (capacitive PE) of the other fieldbus module (Fig. 4-5).
This method prevents currents flowing through the cable screens.
•Connect the terminals 71 and 72 between the fieldbus modules via paired cables (e.B. green and yellow).
Direct connection to the host (cable 2a in Fig. 4-4)
•Connect the host cable screen to PE and the controller cable screen to terminal 88. This method prevents currents flowing through the cable screens.
