Documentation:
The millitron sensor can be read by cabling 16 digital inputs on a corresponding I/O card. This macro set allows to read a millitron as a counter in spec by using either an ICV196 or a wago module. The millitron output is a DB25 connector where pins are defined as follow: pin 1 : pin 2 : pin 3 : overflow pin 4 : x1000 pin 5 : ready for measurement = 1 pin 6 : ready for measurement = 0 pin 7 : digital point 0.01 pin 8 : digital point 0.1 pin 9 : 0v DC pin 10 : 0v DC pin 11 : pin 12 : sign 0->+ 1->- pin 13 : x800 pin 14 : x400 pin 15 : x100 pin 16 : x80 pin 17 : x40 pin 18 : x20 pin 19 : x10 pin 20 : x8 pin 21 : x8 pin 22 : x4 pin 23 : x2 pin 24 : x1 pin 25 : SETUP WAGO : The macro counter method is used. ICV196 : The old pseudo counter method is used: Three counters must be defined in spec to get the readings. Use the macro millitronsetup (see usage below) to configure the card and assign the counters When using an ICV196 this macro set supposes that the millitron is cabled using 1 connector (J1, J2 or J3) by device. Each connector is clabed as follows : bit 0 (mod 32) : x1 bit 1 (mod 32) : x2 bit 2 (mod 32) : x4 bit 3 (mod 32) : x8 bit 4 (mod 32) : x10 bit 5 (mod 32) : x20 bit 6 (mod 32) : x40 bit 7 (mod 32) : x80 bit 8 (mod 32) : x100 bit 9 (mod 32) : x200 bit 10 (mod 32) : x400 bit 11 (mod 32) : x800 bit 12 (mod 32) : x1000 bit 13 (mod 32) : val x 0.1 bit 14 (mod 32) : val x 0.01 bit 15 (mod 32) : sign bit 16 (mod 32) : ready bit 17 (mod 32) : overflowIn the case of ICV196: up to 3 millitron devices can be read. There is on cable per device connected to a Icv196 connector. We associate a pseudo counter per each Icv196 connector even if there no millitron device connected. | ||||||

Usage: millitron_config(mne, type) Called by spec at config time. millitron_cmd Usage: millitron_cmd(mne, cmd, p1,p2) Called by spec to read values _milwagoread Usage: _milwagoread(key) Perform the actual reading on wago and convert values millitron_globals Usage: millitron_globals _millitronread Usage: _millitronread () For ICV196 / Reads J1, J2 and J3 and set the corresponding counters (32 channels per connector) If en error occurs (not_ready or overflow) the corresponding counter is set to -88888 If the millittron is disabled (cmd millitronoff) the 3 counters are set to -99999 The command DevMultipleChannelRead returns 12 values of 8 bits (12*8=96 channels). _millitron_getval Usage: _millitron_getval (tabval,conn) Returns the decimal value of one millitron (one connector) (ICV196 only) _millitron_ready Usage: _millitron_ready (tabval,conn) _millitron_overflow Usage: _millitron_overflow (tabval,conn) _millitron_getbit Usage: _millitron_getbit (tabval,bit,conn) returns the value of one bit | ||||||
