Process data words (PZD) (16 bits) 1 word... 6 words
Parameter data words (PCP) (16 bits) 0/1 word
INTERBUS code (ID code) Decimal: 227 or 3 (no PCP); hex: I3 or 3 (no PCP)
Maximum PDU length 64 bytes
PCP services supported Initiate, Abort, Status, Identify, Get-OV-Long, Read, Write
No. of stations Depends on the host system (I/O range), max. 63

Communication time • Sum of scan time and processing time in the
fieldbus stations. The times are independent of one another.
• Processing time in the controller:
– Parameter data and process data are independent of each other
– Parameter data (PCP): Approx. 30 ms + 20 ms tolerance
– Process data: Approx. 3 ms + 2 ms tolerance
Electrical connection Screw terminals

DC voltage supply Internal
for the function module • External,
– Only required if the communication ring must not be
interrupted by a bus device being switched off
or failing
– Power is being provided via a separate power supply
– +24 VDC ± 10%, max. 90 mA per function module
– X3/59 can be loaded with a maximum of 3A when the supply
voltage is looped through to other bus devices
Isolation voltage to reference earth/PE 50 V AC
Ambient temperature Operation: –20 ... +60ºC
Transport: –25 ... +70ºC
Storage: –25 ... +60ºC
Climatic conditions Class 3K3 to EN 50178
(no condensation, average relative humidity 85%)
Note:
Two LEDs are located on the function module to indicate the communication status.
Important:
The internal or external DC supply to the "controller inhibit" terminal (X3/28) is provided
independently of the internal or external DC supply to the function module.
Tip:
The external DC supply to the function module is provided via terminals X3/59 and X3/7
(see connection diagrams above).
