Target Series 90-70 programmable controllers requires the following:

A TCP/IP Ethernet communications module (IC697CMM741H, PROM version 1.12 or later).

Supporting LAN software (IC651ENS042, containing GSM version 2.09 or later, TCP executive 1.28 or later, and TCP/IP configuration editor 1.02 or later)

CPU firmware must be release 4.12 or later

Target Series 90-30 programmable controllers require the following:

A TCP/IP Ethernet communications module (IC697CMM321).

CPU firmware must be release 5.0 or later

If you are using Logicmaster:

Logicmaster version 4.0 or later must be used with Series 90-70 programmable controllers.

Logicmaster version 6.0 or later must be used with Series 90-30 programmable controllers.

 Warning: Do not use the Series 90 TCP/IP Communications enabler with a Series 90-70 programmable controller using C-blocks in the ladder unless the Series 90-70 CPU has been upgraded to version 6.0 firmware. The programmable controller may crash otherwise.
