Product Description
2. Product Description
The TIC 253 respectively TIC 254 provides a connection for the bus system Profibus-DP
(V0) for the drive units TCP 350 and TCP 3000 respectively TM 3000. If not stated other-
wise the designation "TIC" applies to the TIC 253 and also to the TIC 254.
Abb. 2-1 Description of the front panel
Connection options The TIC offers connection options for the Profibus-DP by means of a 9-way Sub-D sok-
ket (TIC 253) respectively by means of two B-coded M12 connectors (TIC 254).
2.1 Delivery
Included with the delivery of the TIC 253/254 are the following items:
• Unit TIC 253 respective TIC 254
• CD with GSD file and graphics for inclusion in the Profibus configuration tool.
2.2 Proper Use
The TIC serves the purpose of connecting the aforementioned drive units to the Profi-
bus-DP (V0). The type of protection stated for the TIC 254 can only be attained in the
case of correctly fitted rubber stoppers to the address selector switches and the service
connection as well as with connected Profibus connectors, respectively connector with
terminating resistor.

Product Description
2.3 Improper Use
Improper is:
– Uses not covered above, and, in particular,
– Connection to pumps and units which is not permitted in their operating instruc-
tions.
– Connection to units which contain touchable and voltage carrying parts.
Improper use will cause any rights regarding liability and guarantees to be forfeited.

Installation
3. Installation
3.1 Preparations For Installation
➡Connect the Profibus cable to the TIC and secure it against inadvertent loosening by
screwing it down. When doing so, note the applicable regulations and recommenda-
tions for installing a Profibus system.
➡Set the address selector switch to the Profibus address intended for this instru-
ment.
➡TIC 254: fit the rubber stoppers to the address selector switches so as to attain the
type of protection stated. The stoppers must be inserted straight and as deeply as
possible into the holes.
➡To configure the TIC use the enclosed GSD file. Information on this can be found
with your Profibus configuration tool and in the see Chap. 5., page 9.
3.2 Profibus Connection
The Profibus is connected to this box. The pin arrangement is in accordance with the
Profibus standard. Thereby the functions are supported in accordance with the pin assi-
gnment in the table below. It is recommended to tighten the securing screws of the plug
to prevent unintentional disconnection of the plug.

Operation
4. Operation
Before operating the TIC for the first time the valid and unique serial interface address
has to be set by means of the Profibus address selection switch. Alterations to the
address during operations are not permissible.
Illuminating Displays
This LED provides information on the general unit status and the communication with
the TIC unit. Upon switching on there is a test phase of approximately one second for
the LED. Only thereafter will the Table 4.0.1 on page 8 be valid.
Please note
☞
In the case of the TCP 350 (TIC 253) the time which elapses between switching on the
instrument until the Profibus is available may amount to approximately
15 seconds!

Maintenance And Service
8. Maintenance And Service
The unit requires no maintenance. A damp cloth can be used to wipe away any dirt
which has collected on the front panel. Ensure that the unit is first disconnected from
the mains power supply.
Do Make Use Of Our Service Facilities!
In the event that repairs are necessary a number of options are available to you to ensure
any system down time is kept to a minimum:
• Return the unit to the manufacturer for repairs;
• Replace with a new value unit.

Comment
Data field in the output data is
not used. The column "Data"
describes the format in the
data field of the input data.
The column "Data" describes the
format of the information to be sta-
ted in the output data.
Example
Read standby:
A-data: 1, 4, 1, 28
--> E-data 65, 4, 1, 28, 0
(standby is off)
Switch standby on:
A-data: 2, 4, 1, 28, 1
--> E-data 66, 4, 1, 28 (ok)

Valid Parameters
The data appear left aligned in the corresponding data fields, excess digits are of no si-
gnificance. The following formats are possible:
– byte: 1 byte
– word: 1 word (d0 = low byte, d1 = high byte)
– dword: 1 double word (4 Byte, low byte/word first)
– real: Floating point number in accordance with IEEE 754 (4 bytes, low byte
first)
➐Bit 5 1: Insufficient oil,
0: Sufficient oil
Bit 3 1: Overtemperature,
0: No overtemperature
➑Field of the data type stated: first byte contains the number of subsequent elements, for
example:
p349 (field of byte): 7, 84, 67, 80, 32, 51, 53, 48 --> 7 elements: "TCP 350"
p360 (field of word): 1, 6, 0 --> 1 element (word = 2 Byte): value 6
