The sserial ports on the 7I76 are channels 1 (Field I/O) and 2 (7I76 sserial expansion)
so sserial_port_0=020 (if you want mode 2 on the 7I76 field I/O section)
so sserial_port_0=020 (if you want mode 2 on the 7I76 field I/O section)

Thx for the explanation of the sserial_port it's really useful, however I probably should have phrased the question better. I can't see the 7i76, hence I was looking at the sserial_port setting as something that might be preventing me from seeing it.
My intent is to use the 7i76 for additional IO as I don't have enough ports on the 7i96 for limit switches + tool changer + other items. From the manual and your message it looks like I should be setting it up for mode 1 (all IO plus the analog ports). So that would be a config string of:
halcmd: loadrt hm2_eth board_ip="10.10.10.10" config="sserial_port_0=010"
This issue I have is that when I do that I only see 51 pins which I'm pretty sure is just the 7i96s as per below. Any other hints as to what mistake/omission/tests I can do to verify I've got it setup correctly?

The reason I mentioned the sserial_port_0 is that your original example would have disabled the 7I76.
The 7I76 is still not being detected
So it may be cabling or power
So you have both 5V and field power?
7I76 W1 and W3 Left?
Here is what I get running a 7I96S+7I76 with 7i96s_7i76d.bin firmware:

Thx, I’m suspicious of the cable.
I’ve tested it with power to the board and power via the db25 cable (swapping the jumpers to suit), both times the LED’s were on and green.
I’ll double check the jumpers when I get home.
I’ve got power to the field (24v).

With logic power coming via the DB25 (5v) and field power via TB1 (24v) I've got:
W1 = right (VIN SEP)
W2 = left (5v FPGA)
W3 = left
W1 = right (VIN SEP)
W2 = left (5v FPGA)
W3 = left

I've bench tested the continuity of the pins with my volt meter, they're all connected.
I've checked pin 1 against the diagrams and I think I've got it correct but I might have misread it.
Here's a pic of the cable with pin 1's aligned (note the 26pin end has a socket on it to make it easier to test) the 26 pin locating boss is on the left (first pic).
Last pic is of the cable installed.

W1 must be in the left position

Yahtzee!!!!
I see the 7i76 now, thx a bunch for your assistance and patience.
