PCB Design, STM32 SPI

Description

Dimensions: Minimised, to suit.
Supply Power:24VDC.
Output Logic Level & Power:24VDC, PNP, 1A per output channel with 8 off being configurable as NPN or PNP on motor control connector.
Input Logic Level & Power:24VDC, PNP, 8 off being configurable as NPN or PNP on motor control connector.Inputs & Ouputs to be SPI for speed and future proofing
I/O Power Distribution:- 24VDC.o Bank of 24V & 0V next to each I/O section.
I/O Isolation.All I/O to be optically isolated.
I/O Count:32 pluggable Inputs:- 8 of which to include local (on same plug) power (24Vdc & 0Vdc) & teach output (Photocell Connections). I.e. 8 time 4 way connectors (24v, 0V, Signal, Teach (switched 24V)).- 8 of which to be echoed between machine control Input connector & customer Input connector.- 8 of which to be echoed between machine control Input connector & Bespoke Control connector.- 6 of which to be echoed between machine control Input connector & Ray connector.32 pluggable Outputs:- 8 of which to be echoed between machine control Output connector & single pole pluggable change over relays rated at 230VAC/24VDC 6A minimum. Outputs from relays to be fused at 5A and taken to Customer Output connector. - 8 of which to be echoed between machine control Output connector & Bespoke Control connector.- 6 of which to be echoed between machine control Output connector & Ray connector.- 6 to be PT100 temperature sensing inputs
I/O Indication:Led indicators for all Inputs & Outputs.
Motor control.Analogue I/O:- 5 x 0-10Vdc analogue Outputs.Encoder Inputs:- 5 x Standard DIO NPN Inputs (configurable PNP/NPN Inputs)Control Inputs.- 2 x NPN (configurable PNP/NPN Inputs).Control Outputs. - 2 x NPN (configurable PNP/NPN Outputs).Serial Connection:- RS485. Full Duplex. - RS232- Ethercat an option?Processor: - Capable of servicing I/O at a 1ms cycle time. Maybe STM32. Processor pluggable
