Summoner summon monster SLA

[Renen]

When does the summoned monster act? My DM argues it appears and acts on the next time my turn comes around. I think it appears right away, and gets to attack the same turn, because its cast as a standard action.

[chaoseffect]

You are correct, it attacks the same turn it comes out.

[Renen]

does it get summoned on the same turn?

[chaoseffect]

You cast it as a standard action, so yes.

DESCRIPTION
This spell summons an extraplanar creature (typically an outsider, elemental, or magical beast native to another plane). It appears where you designate and acts immediately, on your turn. It attacks your opponents to the best of its ability. If you can communicate with the creature, you can direct it not to attack, to attack particular enemies, or to perform other actions. The spell conjures one of the creatures from the 1st Level list on Table: Summon Monster. You choose which kind of creature to summon, and you can choose a different one each time you cast the spell.

Summoner - Summon Monster:

Starting at 1st level, a summoner can cast summon monster I as a spell-like ability a number of times per day equal to 3 + his Charisma modifier. Drawing upon this ability uses up the same power as the summoner uses to call his eidolon. As a result, he can only use this ability when his eidolon is not summoned. He can cast this spell as a standard action and the creatures remain for 1 minute per level (instead of 1 round per level). At 3rd level, and every 2 levels thereafter, the power of this ability increases by one spell level, allowing him to summon more powerful creatures (to a maximum of summon monster IX at 17th level). At 19th level, this ability can be used as gate or summon monster IX. If used as gate, the summoner must pay any required material components. A summoner cannot have more than one summon monster or gate spell active in this way at one time. If this ability is used again, any existing summon monster or gate immediately ends. These summon spells are considered to be part of his spell list for the purposes of spell trigger and spell completion items. In addition, he can expend uses of this ability to fufill the construction requirements of any magic item he creates, so long as he can use this ability to cast the required spell.

Point out the bolded texts to him. The Summoner's Summon Monster spell-like ability, while based on the Summon Monster spell, specifically states you can cast it as a standard action, rather than a full-round action (which is what is required to cast a spell with a cast time of 1 round).

[Renen]

so, spells cast as a full round action dont take effect until next turn, and spells that are cast as a standard action, take effect right away?

Could you please post a link to that, so I can show my DM this thread?

I think you just have to show him this

Casting Times: there are the related rules. Only spells with a casting time of 1 round or greater don't happen immediately. EDIT: forgot the url >_<

With that said, I've never actually played the 1 round casting time RAW, so I'm not sure if a non-SLA-by-Summoner summoning would get its actions immediately as it comes in and then again on your turn or what.
