• 2 multifunctional integral passive digital outputs
1)
• 2slo
ts for operating optional expansion modules
– PROFIBUS DP (if 7KM PROFIBUS DP expansion module is used)
1)
– Modbus RTU (if 7KM RS485 expansion module is used)
– Switched Ethernet PROFINET (if 7KM Switched Ethernet PROFINET expansion module is
used)
1)
– Up to 8 plug-in digital inputs (if two 7KM 4DI/2DO expansion modules are used)
1)
– Up to 4 plug-in digital outputs (if two 7KM 4DI/2DO expansion modules are used)
1)
– 3 analog inputs (if 7KM I(N), I(Di󹪜), analog expansion module is used)

Note
The PA
C4220 supports 2 expansion modules. One of these may be a communications
module (e.g. 7KM PROFIBUS DP, 7KM RS485 or 7KM Switched Ethernet PROFINET expansion
module).
1)
This function will be av
ailable at a later time via a FW update.
Gateway
• Modbus gateway for integrating purely Modbus RTU devices into an Ethernet network
(Ethernet Modbus TCP ⇔ RS485ModbusRTU). This gateway function
1)
requires an RS485
expansion module.
• Serial gateway for connecting RS 485 devices that support Modbus RTU and similar protocols.
This gateway function
1)
requires an RS485 expansion module.
1)
This function will be available at a later time via a FW update.
Memory
• Adjusted device parameters are permanently stored in the device memory.
• Extreme values (maximum or minimum) are permanently stored in the internal device
memory
1)
. Values can be reset via SENTRON Powercon󹪝g, the communication interface or
directly on the device via the menu.
• Internal clock in the device (retains values during brief interruptions)
• Storage of load pro󹪝les (retains values during brief interruptions)
1)
• Storage of events (retains values during brief interruptions)
1)
1)
This function will be available at a later time via a FW update.
Response in the case of power failure and power restore
In the event of a power failure, the power information recorded up to that point is not lost.
