2. Functional Description
The C5 compact is mounted on a 35 mm mounting rail. The earthing occurs with a plug-in
contact or terminal connection X2.19/20.
2.1 Real-time clock
The integrated real-time clock is maintenance-free (no battery) and operates without power
supply for approx.30 days. After this time it must be adjusted again. A read out parameter
indicates the validity of the date and time. The control shall remain switched on min. 30 minutes
for complete loading. Leap years are recognized automatically up to the year 2099. Date and
time can be read and set via COMBIVIS or the control program.
2.2 HSP5/485 interfaces to the inverter/servo axes
Up to four KEB COMBIVERT F5 can be connected via the terminals X1A to X1D. The
connection occurs via reliability RS485 cables, which can be up to 100 m long. A shielded
standard cable with RJ-45 connector is used on the control side and appropriate operator
on the frequency inverter/servo. The process data of the required axes are exchanged by
the control in the cyclic or synchronous mode. Service 50 (1*32 + 2*16 Bit process data) is
used thereby. The parameter channel is free for the PLC program and COMBIVIS access
to the axes. Depending on the used axes the cycle time can be between 1 and 65 ms. The
process data assignment in the axes must be adjusted before starting the cyclic/synchronous
operation in parameters SY.16…31 (if not stored in the axes).
The process data are mapped-in as follows in the image of the control:

2.6 Ethernet interface (X6B/X6C)
The standardized 10/100 base-T interface supports the protocols TCP/IP and UDP/IP. The
two interfaces are internally connected as switch.
The following ports have these functions:
The CoDeSys port is adjusted to 1200 (as standard). The port can be changed with para-
meter Et.03. The control program is processed here by means of CoDeSys (only TCP/IP
possible).
The COMBIVIS port is adjusted to 8000 (as standard). It can be changed with parameter
Et.02. The access of COMBIVIS or other control/visualizations to parameters of the control,
the axes as well as if necessary by the control program dened parameter occurs here. TCP
or UDP is possible as protocol, at which encapsulated DIN66019II data telegrams will be
transferred.
The used IP address can be adjusted with parameter Et.01. In case that a cross-over cable
is used for the connection, make sure that the upper part of the IP address (network number)
is the same and the lower part of the IP address (Node number) is different from the PC IP
address. The IP address may not have been used in the entire connected Ethernet.
Protect C5 against unauthorized access
Each user within a network can take access to the control with knowledge of the IP address.
The C5 should be absolutely protected against unauthorized access. For the protection
• the write access on the COMBIVIS port can be limited with parameter et.09.
• CoDeSys can be protected with a login-password.

2.8 Multi-function switch/button S1
The multi function switch/button is constructed as follows:
run (switch)
stop/reset
clear (button)
The button S1 is assigned with the following functions
Activity Function
Stop --> Run Program is started
Run --> Stop Programm is stopped, all variables are resetted
(reset warm)
Stop --> Clear and hold (> 3 s) until
ERROR LED lights
After releasing the switch all retain variables are
resetted (reset cold)
Stop --> Clear and hold (> 10 s) until
ERROR and RUN LED light
All variables and the boot project are cleared (re-
set origin) after releasing the button.
2.9 File system
The le system consists of an internal ash memory (drive C:). Access can occur via CoDeSys
or directly from the program of the control.
Internalashmemory
This memory is accessed as drive C: and the boot project can be stored, which is automatically
loaded and started when switching on. Any other les (documentation, download lists, prescrip-
tions, etc.) can be stored and read here. The following particularities must be observed:
• Access is possible only to les in the root directory.
• Only short le names (8.3 format) are possible.
• Reading takes place with high speed and can occur also at any time in the time-critical
cyclic operating modes of the control.
• Writing occurs at a slow rate, because the ash must be programmed here. Any data can
be written if the control is in stop condition, but only one le can be opened for writing. If
the control is in run condition, only blocks of max. 32KByte can be written into the opened
le. As soon as this block was completely stored in the background the next data can be
written.
• Data is not physically deleted. First they are internal marked as deleted. Thus the free availa-
ble memory space decreases. The command "leformat" can be used via the CoDeSys PLC
browser. Thus the complete memory is formatted again. All data is irrevocable deleted.
• The deleted memory space can be make available again with the command "lecleanup"
without reformatting.

3. Software
3.1 Programming system CoDeSys
The axis control is programmed with the programming system CoDeSys of the company 3S-
Software (www.3s-software.com). This programming software is free-available in the Internet.
A KEB target information le (TNF) for the control is available as accessories, which contains
all required hardware specications. A library with rmware functional modules is further con-
tained for access to the periphery (axes, real-time clock, switch, LED, le system). The use
of these functional modules is explained in the provided example projects.
The connection to CoDeSys occurs via the Ethernet interface X6B or X6C via IP protocol. For
this the control is connected with a 1:1 cable to the distribution system of an existing rm net
or by means of a cross cable directly to the network interface of a PC. IP-address and port
number can be adjusted at rst via COMBIVIS. TCP/IP (Level2) is selected with the following
adjustments in the CoDeSys communication parameter:
Address (as adjusted)
Port 1200 (or as changed)
Block size 512
Motorola Byteorder Yes
3.2 Parameterizing system COMBIVIS
The axis control can be parameterized and monitored with COMBIVIS. COMBIVIS is free-
available in the Internet (www.keb.de). Access to all axes is possible via the control with
COMBIVIS. The control has the node address 0, the axes have the node addresses 1 to 4.
Connection with COMBIVIS occurs via Ethernet interface X6B or X6C via IP protocol or the
serial interface X6A. IP-address and port number can be adjusted rst via the serial interface
and COMBIVIS. Afterwards the protocol TCP or UDP as well as the correct IP-address of
the control is selected in the COMBIVIS IP protocol driver. The data port number is 8000, if
necessary it can be changed.
The following must be observed on access to axis:
• First the axes must be switched on, then the control, or the function block 'tSetModes' must
call-up in order to make the connection between control and axis. Thus the baud rate between
axis and control is adjusted to the highest possible value and the axis can be accessed via
COMBIVIS. (After power-on reset the inverter /servo starts always with 38,4 KBaud)
• If an axis is operated cyclically or synchronously, only the indirect set addressing can be
used in COMBIVIS. This applies also to download and scope

3.3.2 Ethernet parameter
The following parameters contain the values, which are needed for the communication via
the Ethernet interface.
et.00 MAC address Address 0300h
The MAC address (Media Access Control) is formed of 6 byte. The rst three bytes
contain the manufacturer's code (00-08-FA). Only the lowest 4 bytes are displayed here
„FAxxxxxx“. This address is assigned by the manufacturer and cannot be changed.
et.01 IP address Address 0301h
The IP address consists of 4 bytes and is the clear identication of one Internet partici-
pant (called node by such a way). In case of doubt the network administrator gives the
address to be adjusted.
When using a direct connection of control and PC with a cross cable, this IP address
should be adjusted in such a way that the difference is only in the lowest byte to the
address of the PC's (same network but different node).
et.02 COMBIVIS port number Address 0302h
The port number for the access via COMBIVIS is adjusted with this parameter. The stan-
dard value is 8000 and normally it is not changed.
et.03 CoDeSys port number Address 0303h
This parameter adjusts the port number, under which CoDeSys establishes the connec-
tion. The standard value is 1200 and normally it is not changed.
et.04 IP error count Address 0304h
Serves for the diagnosis of the IP protocol stack.
et.05 TCP connections Address 0305h
This parameter displays the number of active TCP/IP connections.
et.06 UDP connections Address 0306h
This parameter displays the number of active UDP connections.
et.07 PGM logged in Address 0307h
This parameter displays that there is an online connection to CoDeSys. A further login via
CoDeSys is not possible then.
et.08 TCP multicount Address 0308h
This parameter serves only for diagnostic purposes.

et.09 data port password Address 0309h
This parameter denes the write protection password for the COMBIVIS data port. The
programming of the password occurs only via the serial interface. Then this password
must be entered here again for write access via the data port. Error message "operation
not possible" is displayed in case of locked data port write access. Value 0 switches off
the write protection password.
et.10 gateway address Address 030Ah
This parameter determines the IP address of the appropriate gateway. As soon as
a connection to IP slave address outside the own network shall be made by the control
program, this address is used. In case of doubt the gateway address to be adjusted can
be ask for by the network administrator.
et.11 subnet mask Address 030Bh
The decision whether an IP slave address is outside of the own network is determined
with this mask. If this mask is 0.0.0.0 the standard masks are used depending on network
class A, B or C. In case of doubt the subnet mask to be adjusted can be ask for by the
network administrator.
et.12 data port response delay Address 030Ch
This parameter adjusts the response delay for the Combivis-data port in ms. The network
utilization can be reduced by setting of higher values. A value of 0 enables the fastest
communication with the control, but a high network utilization is also generated.
et.14 Link state Address 030Eh
Displays state informations for the Ethernet link.
et.15 Link mode Address 030Fh
Determines the adjustments of the Ethernet interface. Fixed values or automatic recogni-
tion can be adjusted here. The additional clearlock value 32 activates a special behavior,
which corrects link problems automatically with automatic detection on both sides (control
and switch).
3.3.3 Real-time clock
The internal real-time clock is adjusted and/or read-out with the following parameters.
rc.00 time Address 0400h
This parameter displays the time in hours and minutes in a 24-hours format. Writing on
this parameter adjusts the time.
