AC 800M System Communication Mechanism
The data communication between 3BSE018135R1 CI858K01 and the AC 800M controller is accomplished through Dual-Port RAM.
In the System 800xA automation platform, the CI858K01 is used to achieve:
Drive control
Motion control
Condition Monitoring
Equipment Diagnosis
Through this module, the system can achieve:
Centralized monitoring of driving equipment
Real-time control of production equipment
Fault alarm and diagnosis
3BSE018135R1 CI858K01 provides 4 independent serial communication channels (CH0–CH3)
Each channel can be independently configured as RS-232, RS-422, or RS-485 (via hardware jumpers or software settings)
Maximum communication rate supported: 115.2 kbps (baud rate can be set individually for each channel)
Electrically isolated from the system backplane (isolation voltage ≥500 V AC), enhancing interference immunity.
Supports multiple standard or custom serial protocols, including Modbus RTU, Siemens 3964R, ASCII, JK2, etc. (configurable in Control Builder M required)
Each channel is equipped with independent status indicator LEDs (TX, RX, Fault)
Supports hot-swapping (requires system and backplane support)
Does not occupy the communication resources of the AC 800M main CPU; serial data is processed by the module's built-in processor.
The LED type on the front panel of the CI858K01 module
| LED Name | Color | Function |
| RUN | Green | Module operating status |
| FAULT | Red | Module error or malfunction |
| Dbus Rx | Yellow | DriveBus receives data |
| Dbus Tx | Yellow | DriveBus transmits data |
| I/O Rx | Yellow | The I/O bus receives data |
| I/O Tx | Yellow | Data transmission over the I/O bus |
| Tools | Yellow | PC tool communication |
----RUN (Green)
Constantly on → Module is operating normally
Indicates that the communication interface has been activated.
----Dbus Rx / Tx (yellow)
Flashing → DriveBus is communicating
Indicates that there is data exchange between the driving device and the controller.
----I/O Receive/Transmit (Yellow)
Flashing → The control system is communicating normally with the I/O bus.
----FAULT (red)
Off → No fault
