XCell
TM
ATF System with C410:V4B Controller
User Guide
104
The XCell™ ATF
C410v4 controller is capable of remote operation using the standard Ethernet (Profinet)
port onboard, enabling communication to an OPC server (master customer). To activate this control
mode, the selector switch on the Administrator screen must be toggled to OPC.
See section F.2 Basic
Administration Screen (Remote Mode Connection) selector switch
.
1.1
Remote Control Mode
It is possible to set the
XCell™ ATF
to Remote Control Mode from the main screen. With the
control mode set to “Remote”,
the
XCell™ ATF
uses parameters sent from the OPC server
master.
When set to “Local” parameters may be entered from the local Human Machine
Interface.
Instead of using the onboard HMI (operator interface), the Remote control mode is intended to
allow another operator interface (provided by the end user) to control ATF functions, as well as
receive feedback from the ATF controller regarding the ATF status and data acquisition for
historical purposes.
1.2
Input Signals (from Master to
XCell™ ATF
)
The master, a system with an OPC server sends output data to the slave device (
XCell™ ATF
) in
its configuration, which becomes input for the
XCell™ ATF
controller. The input signals from
Master to X
Cell™ ATF
are directly written to the Input data block parameters
defined in “
Input
Signals (from Master to XCell™ ATF)” tables
(provided the system is in remote control mode and
the selector switch is set to OPC).
Unlike the Profibus communications, which is divided into several pages, all OPC parameters
are contained within one datablock and each parameter can be sent individually.
When programming commands to the ATF controller, it is recommended to leave parameters
at their previous values to avoid sudden changes.
1.3
Output Signals (to Master from
XCell™ ATF
)
The slave device (
XCell™ ATF
) provides output data, which becomes inputs for the master. The
output signals from the ATF are updated every PLC scan. The parameters are
defined in “Output
Signals (f
rom XCell™ ATF to Master)” tables to the
OPC outputs. The ATF_Heartbeat is
provided, so the Master can continually monitor the communication integrity.
OPC Configuration for DCS Integration
The XCell™ ATF
controller is configured as a slave OPC client; at the (default) IP address stated
in the Profinet section of this user guide. The
XCell™ ATF controller is
Siemens S7-1200 PLC.
The IP address can be changed to match customer requirements. Both the PLC and HMI IP
address must be on the same subnet and be set to communicate with each other. For factory
default settings and method to make changes, please see Appendix 4 for details.
Black-Box Configuration
Black-box configuration is similar to remote control mode but allows completely remote
operation of the XCell™ ATF system with HMI disabled at the factory. Black
-box configuration
can be requested at time of ordering a new system.
Prerequisites
The XCell™ ATF should be
calibrated and connected to a Bioreactor or other vessel.
