Page 5: Introduction
Introduction 1 Introduction Preface Read this operating manual before putting the device into operation. Keep the operating manual in a place that is accessible to all users at all times. Your comments are appreciated and may assist us in improving this operating manual. Warranty All necessary settings are described in this operating manual. -

1 Introduction Command sequence Config level -> Power controller -> Operating mode Small arrows between words are designed to make it easier to find parameters in the configuration level. DISPOSAL! At the end of its service life, the device and any batteries present do not belong in the trash! Please en- sure that they are disposed of properly and in an environmentally friendly manner. -
Page 7: Connection Of The Interface
1 Introduction Connection of the interface Terminating resistor of the RS422/485 serial interface To ensure problem-free operation of several devices in a line structure, their internal terminating resistors must be activated at the beginning and end. 1. Disconnect the device from the supply voltage 2. -
Page 8: Configuration
A set time of 0 ms means that the IPC 300 responds as quickly as possible. This setting should be de- ployed when using the RS422/485 interface. -
Page 9: Protocol Description
Device address The device address must lie in the range 1 to 255. Address 0 is reserved for broadcast messages, i.e., the instruction is executed by the IPC 300 but not answered. If an instruction with the device address 255 is received in the device, it will always be processed, even if a different device address has been configured. -
Page 10: Chronological Sequence Of Communication
Same duration as t1. Chronological sequence The master sends a data request for slave 1. After the last character is sent, all connected IPC 300 slaves wait for a time of t1. Then the instruction is evaluated. Slave 2 discards the instruction because the device address does not match. On the other hand, slave... -
Page 11: Error Handling
Minimum response time In the IPC 300, it is also possible to set a minimum response time of 0 to 500 ms in the configuration. The IPC 300 will not send back a response before this time elapses (measured since the last character was received), meaning the duration of t1 + t2 is extended accordingly. -
Page 12: Detection Of Bus Errors
2 Protocol description Error Error code for float values Measuring range underflow (Underrange) 0xFF800000 (Negative Infinity) Measuring range overflow (Overrange) 0x7F800000 (Positive Infinity) Other invalid value 0x7FC00000 (Not a Number) Detection of bus errors A bus error will be signaled if the device has an RS422/485 interface and a Modbus telegram is not re- ceived for at least 10 s. -

Page 24: External Inhibit Input And External Digital Input 1 And 2
6 Specification of values via interface External inhibit input and external digital input 1 and 2 The external inhibit input (0x00CD) and the external digital inputs 1 (0x00CE) and 2 (0x00CF) can be written using the addresses 0x00CD-0x00CF. They can be used in exactly the same way as the hardware inhibit and digital inputs on the power con- troller, i.e., to block the power controller or for functions such as the keyboard lock or display switch-off. - Page 26 JUMO GmbH & Co.
