Accessory modules can be connected in whatever order and configuration. Connection to PROFIBUS DP fieldbus is made via two M12, male and female, 5 pins, type B circular connectors, in parallel between them; connectors pinout is PROFIBUS Interconnection Technology specifications compliant (Version 1.1, August 2001). Address as well as termination resistor activation are set via DIP-switches. PROFIBUS DP node is available in two versions with 32 or 48 outputs allocated to solenoid valves on the manifold directly connected to the node. Such outputs correspond to least significant bytes and their allocation is independent of how many solenoid valves are installed. Remaining outputs can be used to control the modules. Byte allocation to additional modules is fully automatic. Both stand alone and integrated components must operate within the current limits of the fieldbus node; please note: the solenoid valves are supplied by OUTPUTS + 24 V DC (pin 4). To compute the maximum current on the OUTPUTS + 24 V DC, please use the following formula: = number of installed modules = maximum total current absorbed by the i-th module on the OUTPUTS + 24 V DC supply rail (please see specifications of the single module) = number of installed solenoid pilots = mean absorbed current per solenoid pilot (please see table below) Series i_EV 2200 "Optyma S" 36 mA 2500 "Optyma F" 54 mA 2500 "Optyma T" 54 mA Series 2700 24 mA (1 W version) / 100 mA (2,3 W version) For each fieldbus node, maximum deliverable current by OUTPUTS + 24 V DC supply is 4 A, moreover the sum of the currents on OUTPUTS + 24 V DC and INPUTS + 24 V DC must not exceed 4 A. Where: = number of installed modules = maximum total current absorbed by the i-th module on the INPUTS + 24 V DC supply rail (please see specifications of the single module) In case total current is more than 4 A, it is mandatory to supply modules exceeding current limit with power supply module K5030.M12.
