the amount required by an I/O module with ...
digital inputs or outputs (EPM−S200 ...
EPM−S305) 0 bytes
2 analog inputs (EPM−S400/−S402) 6 bytes
4 analog inputs (EPM−S401/−S403) 8 bytes
2 analog outputs (EPM−S500/−S502) 8 bytes
4 analog outputs (EPM−S501/−S503) 10 bytes
4 analog inputs res. (EPM−S404) 34 bytes
2 analog inputs TE (EPM−S405) 22 bytes
1 counter 32 bits, 24 V DC (EPM−S600) 21 bytes
2 counters 32 bits, 24 V DC (EPM−S601) 42 bytes
1 counter 32 bits, 5 V DC (EPM−S602) 22 bytes
2 counters 32 bits, 24 V DC (EPM−S603) 8 bytes
